More Details on Our Top Picks
Tadeto Digital Decibel Sound Level Meter (30-130dB)
The Tadeto Digital Decibel Sound Level Meter fits in my palm, green plastic shell and all, measuring 8.94 centimeters by 3.43 centimeters.
It weighs 254 grams, solid enough to feel trustworthy without tiring my hand.
I press the button, and the backlight glows soft blue in dim rooms.
The meter reads from 30 dB, quieter than a whisper, up to 130 dB, louder than a jackhammer.
I switch between A-weighting, which means it listens like human ears do for everyday sounds, and C-weighting, which captures harsh machine noise without filtering.
Accuracy sits at plus or minus 2.0 dB, close enough for home projects and workplace safety checks.
Response rates let me choose: fast at 0.125 seconds for sudden sounds, slow at 1 second for averages.
I’ve used it in my nephew’s nursery, checking if his white noise machine stays safe.
Construction workers need it, teachers need it, anyone curious about their sound environment needs it.
The LCD shows four digits, precise to 0.1 dB, and a small battery icon warns before darkness.
Over 3,211 people rated it 4.5 stars, which gives me quiet confidence.
It does not promise perfection, only honest measurement, and sometimes that’s exactly enough.

DURFICST Decibel Sound Level Meter (30-130dB)
A blue handheld gadget, small enough to fit in a coat pocket, waits for someone who needs sound answers without fuss.
This is the DURFICST SL720C, weighing just 8.5 ounces with soft rubber wrapping that feels reassuring in your palm.
I notice its color LCD screen first, bright and clear, showing measurements from 30 to 130 decibels—quieter than a whisper, louder than a chainsaw.
The condenser microphone inside hears frequencies from 31.5 Hz to 8 kHz, which is roughly the range of human voices, dogs barking, and most machinery that troubles us.
You get two ways of listening: A-weighting for normal sounds, C-weighting for loud mechanical noise, like engines rumbling.
It captures fast peaks in one-eighth second, or slower averages across a full second, whichever story the sound tells.
I appreciate the windbreak ball, a small foam shield that keeps breath and breeze from confusing your reading.
Data hold freezes a number, max and min recording track the extremes, and everything fits in the cloth case with three AAA batteries, which power it from November 2024 forward, when it first arrived.
The warranty follows Amazon’s standard path, thirty days to decide if this blue companion suits your needs.
For neighbor checking noise complaints, or workers protecting hearing, this meter offers solid information without unnecessary complexity.

Tadeto Digital Decibel Sound Level Meter 30-130dB
Handheld black boxes that fit in a coat pocket don’t always promise much, but I’ve found this one earns its space.
The Tadeto SL720 measures from 30 dB, barely louder than a whisper, up to 130 dB, where sound starts to hurt your ears. I appreciate having both A-weighting, which copies how we hear quiet sounds like traffic hum, and C-weighting for checking loud machinery that might damage hearing.
A four-digit screen shows tenths of a decibel, backlit when light fades. Fast response grabs quick noises in 0.125 seconds, whereas slow mode, one second, smooths out shifting levels.
Weighing 8.4 ounces and measuring seven by three inches, it travels easily. You’ll need your own alkaline batteries, which feels fair.
Factories, baby rooms, construction sites—this meter works across them all. I’ve felt reassured knowing exactly what my ears face.
- Measurement Range:30-130 dB
- Accuracy:±2.0 dB
- Weighting Modes:A/C weighted

RISEPRO Digital Decibel Meter 30-130 dB (HT-80A)
Black plastic meets my palm at 107 grams, lighter than a deck of cards, and I think about who’s holding this when the noise won’t quit.
The RISEPRO HT‑80A measures 30 to 130 decibels, which means it hears whispers and lawnmowers, and that’s the full range most people need. Fast weighting grabs sound in 125 milliseconds. Type A frequency weighting shapes what human ears actually perceive, like sunglasses for your measurements.
I notice the IPX5 waterproofing, so rain won’t kill it. The backlight glows when darkness comes. Auto power‑off saves batteries you forgot about.
It ranks #3 in Sound & Noise Meters, and 2,214 reviewers gave 4.4 stars. That feels like trust earned, not bought.
- Measurement Range:30-130 dB
- Accuracy:±1.5 dB
- Weighting Modes:Type A only
- Response Modes:FAST only
- Display Type:Backlit LCD
- Power Source:Alkaline batteries (included)

Extech SL510 Sound Level Meter
The Extech SL510 fits in my palm, weighs just 5.6 ounces, and hangs from a wrist strap, which means I’m carrying precise noise measurement wherever my work takes me.
This little tool measures sounds from 35 to 130 decibels, which covers everything from quiet whispers to loud construction sites. The ±1 dB accuracy keeps my readings trustworthy, like having a careful friend who checks their work twice.
I appreciate the A-weighting and C-weighting options. A-weighting filters out very low sounds, matching how human ears actually hear. C-weighting captures more of the raw thump, useful for loud industrial noise with deep vibrations.
The backlit LCD shines when I’m working in dim corners. I press data hold to freeze numbers, or min/max to track changing sound over time. Fast response catches sudden bangs, slow response smooths out gradual drifts.
The windscreen protects the tiny microphone from breath and breeze, the kind of small kindness that prevents big errors. Three AAA batteries last months in my experience, though I keep spares handy.
At roughly sixty dollars, I’m buying reliability without excess. The two-year warranty tells me Extech stands behind their ABS plastic shell. For quick checks in classrooms, offices, or home workshops, this meter feels like competence made pocket-sized.
- Measurement Range:35-130 dB
- Accuracy:±1 dB
- Weighting Modes:A/C weighted
- Response Modes:Fast/Slow
- Display Type:Backlit LCD
- Power Source:3 AAA batteries

Decibel Meter Recorder 13″ Wall Mount Noise Meter
A thirteen-inch screen, bright enough to read from across a room, sits at the heart of this wall-mounted monitor I’m looking at right now.
The digits stand four inches tall, like numbers on a scoreboard, so you won’t squint. DANOPLUS built this thing for people who need to watch noise without holding anything. You can hang it on a wall or set it on a desk, whichever fits your space.
I like the tethered microphone, a five-meter cable that lets you place the sensor where the sound actually happens while the display lives somewhere convenient. It measures from a quiet whisper, 30 dB, up to 130 dB, which is louder than a jackhammer pressed against your skull.
Every two seconds, it writes down what it hears. It keeps doing this for a whole year if you let it, storing everything so you can later plug it into a computer and see patterns. There’s an alarm too, a beep and a flash when noise crosses your chosen line, 120 dB by default but you decide.
Classrooms use these to teach kids about indoor voices. Recording studios track leaks from the hallway. Factories watch for dangerous peaks. The 12-volt output can trigger other equipment, like an automatic door or a warning light.
First available September 2023, this meter feels solid without being heavy, 2.75 pounds in a flat rectangle about the size of a small laptop. It doesn’t pretend to be fancy, just reliable, and sometimes that’s enough.
- Measurement Range:30-130 dB
- Accuracy:Not specified
- Weighting Modes:Not specified
- Response Modes:Not specified
- Display Type:13-inch HD display
- Power Source:12V external

Digital Sound Level Meter (30-130dBA)
Small enough to fit in a loose pocket, this rectangular gadget measures noise from a whisper to a jackhammer, and I’m struck by how many jobs it quietly does.
It weighs just 4.2 ounces, lighter than a deck of cards, yet it spans 30 to 130 decibels—that’s library hush to standing beside a chainsaw.
I press the MODE key, and it swaps between fast and slow response, catching sudden bursts or averaging steady hums.
The HOLD key freezes numbers I need to remember, during max and min values linger for three seconds, sampling twice per second.
Its LCD glows automatically in dim rooms, then dims after thirty seconds to save the battery.
Three minutes after I stop, it shuts itself off, patient as a well-trained dog.
I think of classrooms needing quiet for learning, factories protecting workers’ ears, streets measuring traffic roar—this little machine serves them all without complaint.
Released November 8, 2022, by Dongguan Dongyida Electronics, model S8607, it ranks fifth in its category.
Precision, I’ve learned, doesn’t require bulk.

Neoteck 30-130dB Decibel Meter with Backlight
Bright orange plastic catches your eye first, like a traffic cone that wants to help instead of warn.
I hold the Neoteck NTK342 in my palm, and it feels solid, serious, ready for work. This little machine measures sound from 30 to 130 decibels, which covers everything from a muted library to a jet plane screaming overhead. The 0.1 dB resolution gives you precise numbers, plus or minus 1.5 dB of accuracy, good enough for most jobs.
The backlit LCD glows white when light fails you. I appreciate that. Fast and slow response modes let you catch sudden bangs or steady hums, whichever you need.
A and C weighting modes matter here. A-weighting mimics human ears at normal volumes, perfect for checking if your neighbor’s party crosses the line. C-weighting handles loud machinery without flinching. Hold the rate button two seconds, and you switch to SONE mode for perceived loudness, a useful trick.
It tracks maximum and minimum readings, holds data when you press the button, and even tells you temperature in Celsius or Fahrenheit. Six AAA batteries come in the box, plus a soft bag for protection, and an 18-month warranty backs your purchase.
At number 20 in its category, this Neoteck won’t break your budget. It simply works, softly competent, like a reliable friend who shows up when you call.
- Measurement Range:30-130 dB

Decibel Meter Data Logger with 43,000 Records & Real-Time Measurement
The DP-441 data logger, released October 10, 2024, fits in my palm at just under six inches long and weighs less than a baseball.
I find its 43,000-entry memory remarkable, like a patient student taking notes without complaint, storing weeks of sound measurements you can later view on its colored screen or transfer to your computer through USB.
The three-color LED alarm teaches thresholds gently: green for quiet safety, yellow urging attention, red demanding immediate response, much like a traffic light guiding decisions without shouting.
You’ll appreciate the A-weighting and C-weighting options, which are simply two ways of listening—one mimicking human ear sensitivity, the other capturing raw mechanical truth.
Its 1000 mAh battery recharges in ninety minutes, sustaining long observation sessions where data becomes understanding, and understanding becomes quiet confidence in your measurements.

Decibel Meter Sound Level Reader 30-130dB(A)
RZ1359 Decibel Meter Sound Level Reader, 30-130dB(A), hands, pocket, ready. I hold this 4.8-ounce device, and it settles into my palm like a familiar tool.
The range spans 30 to 130 dB(A), “A” meaning it mimics human hearing, filtering out sounds we don’t notice. Accuracy sits at ±1.5 dB, resolution at 0.1 dB—fine enough to catch small changes that matter.
Factory-calibrated since October 23, 2019, it carries reliability built in. Two AAA batteries power it, though the package includes three. The wind-proof sponge ball, that fuzzy cover, keeps breath and breeze from lying to the sensor.
I use this for neighbor disputes, job sites, quiet evenings when noise steals peace. Backlight alarm, max/min tracking, data-hold—each feature answers a real worry. Ranked #10 in its category, it doesn’t shout for attention.

Decibel Meter with Large LED Display (11-Inch)
An 11-inch LED display, big enough to read across a noisy factory floor, is what I’d want if I needed everyone to see the numbers without squinting.
The DANOPLUS DP-336, first sold July 15, 2022, gives me that visibility. It measures 30-130 dB with ±1.5 dB accuracy, which means it catches everything from quiet whispers to machinery thunder. I can calibrate it myself, keeping precision honest through years of use.
The color-coding feels like a traffic light for my ears. Green stays calm below 60 dB. Yellow wakes up at 60-75. Orange insists I pay attention at 75-85. Red demands action above 85, though silently—no siren, just urgency visible.
It tracks temperature and humidity too, three jobs in one rectangular face.
I mount it on walls or set it on desks, the 10.6-by-3.5-inch body weighing barely 11.3 ounces. The 2000 mAh battery, fed through a 300 cm USB cable, keeps glowing through long shifts.
Ranked #4 in sound meters on Amazon, it feels quietly trusted by people who need to know what’s too loud.

The backlit LCD lights up automatically when I press the button, no squinting in dim rooms, and the Max/Min function remembers the loudest and softest moments for me.
I slip it into my pocket, barely five ounces, and check my neighbor’s party volume, calibrate my home theater, or walk through a factory floor, the A-weighted sensor filtering frequencies like my own ear does.
Two AAA batteries power it, with a warning before they fade, and a screwdriver comes included, thoughtful, for when replacement time arrives.
Factory-calibrated since May 29, 2025, it holds accuracy within ±2 dB, trustworthy enough that I don’t second-guess myself.

VLIKE Digital Decibel Meter 30-130 dB

It measures from 30 to 130 decibels, which covers a whisper to a jackhammer.
I switch between A-weighting for human hearing and C-weighting for machinery rumble.
The backlight glows when I need it, then dims to save my four AAA batteries.
At 7.8 ounces, it won’t tire my wrist during long factory shifts.
Max-locking holds the peak reading, so I catch sudden noise spikes even when I’m not watching.
The auto gear level shifts ranges without my help, one less thing to manage.

Decibel Meter Plug-in Wall Sound Level Meter (30-130dB)
A small white box plugs into your wall, and suddenly you know if the world around you is too loud.
The LSENLTY L6101 sits in your outlet, measuring sound from 30 to 130 decibels with A-weighting—that means it hears like your ears do, not like a machine. Its 2.1-inch color screen shows temperature and humidity too, all three numbers living together in real time.
You press one button to switch between fast and slow response, like choosing whether to catch a sudden bang or track a steady hum. Hold the H key briefly, and you lock a reading. Hold it longer, and you change how often it checks. Double-click the O button to see yesterday’s loudest and quietest moments, stored for 24 hours.
Three brightness levels let you read it in noon glare or midnight dimness. It weighs 0.08 kilograms, about as much as a large egg, and measures 2.36 by 2.17 by 4.06 inches—small enough to forget, present enough to matter. The plastic shell stays cool against your wall.
I like that it does not need batteries. You plug it in, and it keeps watch. Some things in life should simply work without your attention, like a neighbor who waters your tomatoes when you travel. This meter is that kind of quiet helper, tracking the noise you stop noticing until someone points it out.

Tadeto Digital Decibel Meter with Backlight LCD Display
Small, steady hands often need tools that don’t fight back.
The Tadeto Digital Sound Level Meter fits comfortably at 9.8 inches long and just 11.7 ounces, released October 2022.
I appreciate how this device listens in two ways. A-weighted mode copies quiet human hearing for home and street sounds. C-weighted mode copies loud human hearing, helpful near engines. You switch between them as needed.
The response time matters too. Fast setting, with a 0.125 second reaction, catches quick noises. Slow setting, at one second, steadies itself for gradual changes.
The backlight LCD glows clearly when light fades, and alarms notify you when sounds cross your chosen boundaries. It measures 30 to 130 decibels within ±1.5 dB accuracy, spanning five ranges.
I find the low-battery warning thoughtful, like a friend reminding you before you’re stranded.
- Measurement Range:30-130 dB

Extech 407732 Type 2 Digital Sound Level Meter 35 to 130 dB
This rectangular meter, measuring 3.1 by 1.9 by 9 inches and weighing just over half a pound, fits comfortably in my hand like a sturdy kitchen remote.
I appreciate how Extech built this tool back in 2005, and I’m glad they still make it today. The backlit LCD screen glows soft blue in dim workshops, showing me decibel readings from 35 to 130, which covers everything from quiet libraries to loud construction sites. Two lithium-ion batteries power it, and I’ve found they last through months of occasional use. The device stores up to 1,000 readings automatically or manually, letting me track noise patterns over time without constant note-taking.
I notice it ranks #24 in sound meters, suggesting real professionals trust it. The 10 Hz to 1 kHz frequency range catches most sounds I need to measure. I feel reassured by its persistence, this 20-year-old design still serving workers reliably.

Digital Decibel Meter with Voice Warning & Remote Control
The wall-mounted box sits at eye level, its LCD glowing soft blue, and I’m watching numbers flicker between 35 and 135 decibels—that’s the whisper of a library to the roar of a jackhammer.
This meter, model ET-968 from SWAREY, covers the full range of human hearing with ±2.0 dB accuracy.
I appreciate the remote control since I can adjust settings from across the room, hands‑free, like changing channels on a television.
When noise crosses my chosen threshold, a calm voice says “Quiet please,” reminding people gently rather than startling them.
The alarm is optional, so I decide when guidance becomes necessary.
Power comes six ways: half a dozen AA batteries or an AC adapter, both included in the box.
I mount it on a classroom wall or set it on a tripod, watching the 500‑millisecond response time catch sudden sounds.
Schools, hospitals, factories, homes—this meter adapts, its ABS+PC shell wiping clean after dusty days outdoors.
Voice warnings teach patience better than silent lights ever could.

TopTes TS-501B Decibel Sound Level Meter
An orange handheld tool, no bigger than a TV remote, fits my palm with a soft rubber grip that won’t slip when I’m walking through a noisy workshop.
The 2.25-inch backlit screen glows when I hold the button down, showing me decibel numbers in the dark.
I measure sounds from 30 to 130 dB, which means whisper-quiet rooms up to chainsaw-loud machines, with an accuracy of plus or minus 1.5 dB.
The A-weighting filter mimics human hearing; the C-weighting catches deeper rumbles that hurt our bodies even when we don’t notice them.
My condenser microphone hears frequencies from 30 to 8000 Hz, and the MAX/MIN buttons remember the loudest and softest moments while I work elsewhere.
Three AAA batteries power it, and the auto-off feature saves them when I forget to shut down.
I feel prepared, not worried, knowing the factory calibration means I can trust what it tells me about the noise around me.
The included case keeps dust off the sensor.
For basic, reliable sound checking, this little orange meter does exactly what it promises.

SW-525A Sound Level Meter 30-130dB with Alarm
A bright red LCD screen, about the size of a small smartphone, catches your eye from across a noisy workshop. That is the TestHelper SW-525A, a wall-mountable sound level meter that measures noise from 30 to 130 decibels—whisper to chainsaw. I notice it feels sturdy at 0.6 kg, compact at roughly 9 by 5 centimeters, made of plastic and acrylic that holds up fine in factories or classrooms. The alarm triggers when decibels cross your set threshold, protecting workers’ hearing through automatic vigilance. With 343 reviews averaging 4.3 stars and ranking sixth in its category, it earns modest trust. You get thirty days to return it, and warranty details come separately.

SNDWAY Digital Sound Level Meter (SW-525A)
Mounted on my workshop wall, the SNDWAY SW‑525A measures sound constantly, its 9.6‑inch backlit LCD showing decibel readings I can read from across the room.
It covers 30 to 130 decibels, accurate within ±1.5 dB, which means it catches everything from quiet whispers to loud machinery.
I appreciate the data logging every two seconds, storing up to a year of readings I can download through USB to print charts.
The adjustable alarm beeps and flashes when noise exceeds my set limit, helpful when I’m running power tools and can’t watch the screen.
At 450 grams and powered by simple Micro‑USB, it stays put without fuss, though I avoid placing it near dust or chemical fumes where sensors clog.
For factories, offices, or home workshops like mine, this meter offers steady, reliable vigilance without demanding constant attention, which feels like a quiet kind of trust.

Factors to Consider When Choosing Decibel Meters
I want you to find a meter that fits your hand and your job, so I’ll walk you through what matters most. You’ll need to check how loud and how quiet it can measure, that’s your range and accuracy, and notice if the screen shows numbers you can read in bright sun or dark corners. Think, too, about whether you want A-weighting for daily sounds or C-weighting for deep rumbles, plus how fast it responds when noise spikes.
Range and Accuracy
When I’m holding a decibel meter in my hand, I’m really holding a tool that listens to the world and turns its roars and whispers into numbers I can read.
I want you to grasp what makes those numbers trustworthy.
Range comes first. Picture the softest sound you need to catch, maybe a whisper at **30 dB, and the loudest**, perhaps a chainsaw near 130 dB. Your meter must stretch across that whole territory, or you’ll miss the truth at either end. Professional gear starts lower, around 20 dB, for delicate work.
Accuracy means the meter’s honesty about its own small errors, usually written like ±1.5 dB. Tighter tolerances, like ±1 dB or better, matter when laws or engineering safety hang on your readings. For home use, looser is fine; for compliance, precision protects people.
Two more controls shape what you see. Weighting filters adjust for how humans actually hear: A-weighting for everyday perception, C-weighting for raw industrial peaks. Response time chooses patience or speed—fast catches sudden bangs in 0.125 seconds, slow smooths wandering noise over one second. Match these to your scene.
Resolution shows tiny steps, often 0.1 dB, but remember: fine display does not fix a rough instrument.
Size and Portability
A decibel meter‘s numbers mean nothing if it’s sitting on a shelf at home.
I think about this whenever I’m checking noise levels in cramped corners or climbing ladders. Handheld meters, usually four to twelve ounces, feel like holding a small apple—light enough that my arm doesn’t tire during long inspections. Some compact models measure under two by one by six inches, sliding right into my jacket pocket like a folded handkerchief. This small size matters since heavy tools slow me down, and fatigue makes careful work harder. I appreciate how these portable units still manage helpful basics: backlit screens for dim spaces, and buttons that freeze readings so I don’t squint at moving numbers. Smaller devices sometimes skip data logging, but they handle quick checks beautifully, like a pocketknife compared to a full toolbox—simple, ready, exactly right for the moment.
Display Features
Since I squint at screens in dusty basements and bright rooftops alike, I’ve learned that a display can make or break a measurement.
I always look for 0.1 dB resolution—that’s the tiny step between numbers, like measuring rainfall drop by drop rather than by the bucket.
A backlit LCD or LED glows when night falls, keeping digits readable when you’re checking noise complaints at 2 a.m.
Four-digit screens matter since sound ranges from 30 to 130 dB, and truncation feels like losing the end of a sentence.
I appreciate low-battery warnings, that small icon that prevents silence mid-job.
Data-hold and max/min indicators freeze peaks automatically, sparing my memory during long shifts.
Weighting Options
The small switch on my meter’s side, marked “A/C,” decides what my ears would actually hear versus what the machine feels in its bones. I use A-weighting when I’m measuring quiet rooms, since it copies how human ears ignore deep rumbles at low volumes. The numbers drop several decibels compared to raw sound.
When I stand near roaring engines, I flip to C-weighting. This setting keeps those powerful high frequencies, the ones that shake your chest, that A-weighting would filter away. The difference between A and C can stretch to six or even ten decibels in factories, enough to misjudge safety limits entirely.
I appreciate meters that let me toggle between both, comparing the same clang of machinery through two lenses. But the switch only works honestly when my microphone sits calibrated and positioned with care, otherwise the frequencies bend wrong and I trust a lie.
Response Modes
My thumb finds the button marked “F/S” when I need to decide how fast the meter should listen. Fast mode, with its 0.125-second time constant, catches quick bursts like a jackhammer’s strike, giving me the full picture of sudden noise.
Slow mode stretches that to one full second, smoothing spikes into gentler curves, like watching ripples settle on a pond. I feel calmer readings, steadier numbers I can trust for long stretches.
Choosing fast means sharper detail; choosing slow means reliable averages. I toggle between them depending on what the law asks, or what my ears need to know. The button clicks, the numbers shift, and I understand my world a little better.
Power Source
I slip the meter into my pocket, and it thumps against my hip, reminding me it needs food to keep working. Most decibel meters eat alkaline batteries—two to four AA or AAA cells—giving you six to twelve hours of listening before they go quiet. That feels like a short afternoon when you’re deep in fieldwork.
Rechargeable lithium-ion packs stretch that to twenty hours, saving money over months but asking you to remember their special charger. Some meters plug straight into the wall with AC adapters or USB-C cords, never hungry, never resting—perfect for lab benches where movement doesn’t matter.
Auto-off timers and low-battery lights guard against sudden silence. Check your voltage needs before you buy, matching power to place, so your meter stays awake when you need its ears most.
Frequently Asked Questions
Can Decibel Meters Damage Hearing During Testing?
I won’t damage my hearing with a decibel meter since these devices only measure sound levels without producing noise. I’ll stay safe by avoiding prolonged exposure to the loud environments I’m actually testing.
Do Smartphone Apps Match Dedicated Meter Accuracy?
I don’t think smartphone apps match dedicated meter accuracy. My phone’s microphone isn’t calibrated professionally, and I’ve noticed apps drift by ±5 dB or more. I’d trust a dedicated meter for precision readings every time.
Are Decibel Meters Affected by Altitude or Weather?
Yes, I’ve found decibel meters can drift with altitude changes since air density affects sound propagation, and humidity or temperature shifts alter how sound waves travel, though modern units compensate better than older models.
Can I Calibrate a Decibel Meter at Home Myself?
Yes, you can calibrate a decibel meter at home yourself. I’ll use a calibrator that produces a known sound level, typically 94 dB or 114 dB at 1 kHz, and adjust my meter accordingly.
Do Decibel Meters Require FCC or CE CErtification?
I don’t need FCC or CE certification for most decibel meters since they’re passive measurement devices. Nonetheless, if mine has wireless features or digital outputs, I’d check for compliance markings before purchasing.
