Bought this because of a noisy neighbor above my apartment. Local police department uses it so I bought to be able to get same readings they would obtain if (when) I have to create a noise would be nice if it had a wireless connection ability so it could get its own date/time stamp to make a noise record. Right now, I have to keep my tablet beside it to present date/time when I begin measuring. Not a huge deal, but a nice to have. I have to create the video anyway, so I live.
Bought this for 5-6 times more than those low end products expecting to obtain a high quality one. But no, just the opposite. It worked out of box for about 20 mins then the reading went on its own and did not response to any sound anymore. Also it seems cheaply manufactured - metal part looks dull and plastic parts are roughly fit. I am packing it for a return. Will test a various brand other than Extech.
I picked up one of these to support level match my subwoofer to my main stereo system. It has A and C weighting, and I used C as recommended. It worked amazing for this without needing to understand anything, right out of the box. I also used it to see if the level on the noise machine in my nursery was in the safe range, and adjusted it a little. There's a lot of buttons I probably won't use, honestly, but this is well made. It comes with a wind foam shield which you can use for outside applications. For fast estimates of sound volume (for unofficial purposes, I'm not sure how well calibrated this is) or for comparing two sources to see if they are the same, this is the right tool.I also used this to point out to my wife that the home theater stereo wasn't too loud to do hearing damage. I then pointed out that her yelling at me at how loud the stereo was actually WAS loud enough to do hearing hurt (90db!) and that she should probably volume down. Yeah, that didn't go over so well. I don't recommend using this for spouse volume testing. But for stereo equipment matching, oh yeah, it rocks for that.
This Extech 407730 decibel sound meter is simple to use right out of the box and it works very well. The instructions are easy and simple to understand and everything worked as expected. I had never owned or used a sound meter before, so I wasn't sure what to expect, and someone told me it can be complicated, but it's "So easy a kid could do it", to quote Dr. Leonard "Bones" McCoy from the original Star Trek (Spock's Brain episode)!Having both the "A" and "C" ratings available to use is a amazing thing -- create sure you know which one you should use for your particular app (I did some primary web research to learn more). It measures 40 dB to 130 dB, and I was surprised to search that 43 dB is about my primary background noise in my yard, no wind but birds so, the "Max Hold" function is great; it keeps the highest rating on the display so if you mount the meter remotely, you can still see what it recorded.I mounted it on a primary camera tripod and it worked fine. It actually has a metal tripod mounting thread, unlike some (expensive) digital cameras that use e only nits I can pick are: 1) The small foam wind sock that sticks over the end is beautiful flimsy and it comes off too easily, but not a biggie; and 2) The battery cover is attached with a little Phillips head screw, rather than having a cover that simply snaps on. So you'll need to search a very little #3 Phillips head screwdriver just to remove the batteries, and let's hope you don't have to do this at night or in the [email protected]#$%! seems well created for what it is -- primary plastic case and slightly mushy rubberized push buttons. The display is simple to read (not sure if it has a light, I only used it during the day).Once you familiarize yourself with the instructions, you beautiful much don't have to bother with them again, it's that simple to use. The batteries are the el cheapo type that probably have about 25% of the lifespan of a amazing pair, but otherwise, this is a very nice unit that's probably method overkill for just recording the neighbor's late night parties. I used it for a primary scientific research project and published the results and it worked fine for that.
So far this meter seems to be working alright enough. We have used this on numerous occasions: checking noise level of a window air conditioner to determine if there was any method to dampen the noise level via adding different barriers around window; checking noise level of mowers, tractor, and weed eaters - though we always wear some sort of protective ear gear (plugs or muffs). By measuring equipment we use /have on hand, this gives us a more realistic idea as to what level of noise reduction we wish to target / pay for with future replacement or other "noise producing" equipment. I could use this in my business, as I believe the quality is sufficient for the purposes of a very "limited" sound survey.
No backlight but even worse the auto off function works when youre recording levels, sooo if you’re not hitting a button every 20 minutes it turns off. It’s useless garbage. I got it to do dosiometering and it turns off. I reviewed the specs and it only measures down to 300hz so really not much better than the application on my phone. I got this as a dedicated sound meter to free up my phone but this thing is too worthless to use. And now I’m past the 30 return period. Don’t end up with garbage like me. Buy an application on your phone for 5 bucks or spend 200+ and obtain a true meter. This one is worthless. It’s like buying a handheld recorded that shuts off 20mins in WHILE RECORDING to ‘save power’. Well save your cash and even more power by not buying this.
I did some testing with the product to see how repeatable it is and found the manual range setting to be more repeatable (and probably more accurate) than the auto ranging. I'm measuring some equipment that has a short duration noise spike, which is typically hard to measure. In the quick mode and with manual ranging, it does a amazing job with this and gives a repeatable reading.I don't have anything to calibrate it with, so I can't comment on accuracy, but it appears to read about what I expect it to. The owners manual is adequate, but the user interface is not intuitive, so hold the manual with the tool, as you will need it again if you have not used the tool in a few months. The memory keep feature works as stated and is simple to use. Quality is good, about what you would expect at this price.
I use these for restaurant inspections as a health inspector. It is little enough and light so I don't mind carrying it in my tool bag everyday. It's a luxury item, because most inspectors could care less about proper light levels when there are so a lot of facilities with poor meal temps. I mainly use it on fresh construction, when they have the ability to create adjustments more easily. Works well. Just pop off the protective black cover to reveal the white frosted dome and begin reading.
I'm in the commercial lighting business, and I use this product for reading foot candles nearly every day. It's a bit bulky and I want they'd figure out a method to incorporate the sensor into the unit so you're not always having to use both hands to use the device (the sensor is always flopping around while I'm using the device and juggling a notebook and so on). Seems to be well created and durable. Seems to be quite accurate. The device was more than I wanted to spend on such a tool, but it was recommended to me by others in the industry and it's living up to its reputation.
I purchased this light meter since it's the exact model the AHJ uses. The model I bought is slightly various than the inspectors and electricians already have, and the change was unnecessary and irritating. They added a push button to let the battery cover to slide off, which is located in the middle of the back of the meter body, so the light meter doesn't sit flat on the ground anymore. Other than that, it's a amazing meter at a amazing price.
I believe the unit I received was a 'defective', so I am not making a statement about ALL meters of this model #. If you don't see any other reviews alleging poor readings, right out of the box, then disregard this one as a "one off" event. It would not restart itself, said "cap" (meaning place the cap on, to calibrate) about 80% of the time, even though the cap was already on for calibration. With cap off the readings were all over the is meter was more than twice as pricey as the LT45, but would not work reliably. I ordered the LT45 and it works very well, plus has a backlit display when you need it. about 1/2 the price.
Reasonable compromise between quality and price. Does what the ads claim it will do. Two things in particular that I like about this unit, the first being that it reads a dead 0 on the meter when the lens cap is on the detector lens (think about how problematic that it would be if this were not the case). And the second being that the measured light levels are consistent, you can measure a particular location, and then come back later and measure the same area, and obtain the same reading.I've no idea if the readings are specifically accurate, but for what I'm using it for (verifying that light levels are not adversely affected doing an "LED for Fluorescent" replacement), it works perfectly.
For the price, works great.Purchased this for use in acquiring night light meter readings on roadways. It allows for lux or foot candle measurements. The instruction manual covers the quirky min/max average function. Otherwise, it did a amazing job on the jobsite. The included bag provides for amazing storage and the device is sturdy and works amazing in a commercial e only problem is there is no back light, which created night readings a small difficult. The fact that the light meter was integrated into the device meant there was no extra wires to manage.
Bought this for testing at work...the meter worked fine the first day, had amazing sensitivity and dynamic range. But it broke the second day and we had to buy another one. It just stopped taking measurements. We did all the normal things, replaced the battery, checked cables and fuse, but it was permanently broken.
Does not come with any official certifications. If you need a certificate outlining the calibrations for insurance or manufacturing purposes (we use the meters in ASME testing) then you need to go through Extech themselves or through someone like McMaster Carr who can obtain you those certs.Other than that, the meter was in excellent condition! Worked great, wasn't damaged in any way. The box was a small beat up but the product was fine.
Inexpensive light meter that is worth the price. Only problems are 1 - readings drift up in value over a few mins and 2 - no calibration certificate of any sort. A NIST certificate would be beautiful pricy, however some sort indication of calibration would be nice. I compared this unit for stability under indoor lighting next to my International Light photometer. The Extech drifted significantly more than the other meter. Then again it costs a fraction as much and is portable.

Amazing simple to use and fairly accurate app(depending upon the microphone of the device you are using). The thing I love the most is that it does not irritate you wuth ads, instead it gives you an option to see an ad. I know the devs have to earn cash somehow, so its a amazing feature. I always watch the ad when available.

Used our sound room at work to calibrate. A Samsung Galaxy S8 and this application held tight (nearly the same readings) to a much more expensive meter versus white noise at different volumes. I mainly use this application in restaurants when I can't hear people. I can present the reading and then we resume talking louder and closer.
Superb app. No intrusive permissions asking for every detail of your phone, zone etc. It works precisely, allowing you to calibrate for various microphone levels as each phone will be different. For me the ads did not result it in a negative way, u can close it immediately. The developer can't do this for free! Thank you very much

Seemingly quite good. I won't address audiophile applications because I am not using the tool in that way. I wanted a device that would monitor sound levels in my neighborhood and on construction websites that I drive to so that I wouldn't have to rely on the assertions of others about actual and prospective noise impacts. This device is quite well suited for that. The MAX function allows you to catch peak impact noises, isolating them from the primary noise levels of the try is device was designed as a temporary or moment-to-moment metering device. Individuals who have the need to trap data and transfer a stream to a computer record should look for a various type of tool or a device with a larger set of metering e company delivers the device in calibrated condition, of course, but is inconsistent in its recommendation for calibration through time. In the accompanying user guide, recalibration is recommended before every use, especially if the instrument has not been used for some time. On the company's web site, recalibration is recommended once a year. Recalibration requires an extra device; Extech offers one that costs twice as much as the meter itself. Independent specialists or employees of sound ysis services won't be bothered by the expense, but casual users of the device may search that to be a huge to swallow to hold a tool tuned up that is used only now and then.I metered a tv broadcast whose volume was set in the overlap location for the device's high and low ranges and found the readings to be beautiful much in agreement -- perhaps 1-2 dB apart. This was a rough eyeball comparison, not a serious attempt to determine the meter's consistency. My verdict is that the unit is easily amazing enough for occasional personal party use and even fast professional determinations to tutorial expectations in a context where more extensive noise level studies are planned.

I have an older DB meter that does straight readings. I was looking for something that I could use for averaging and finding peak volumes so I gave this a try. It's not at all expensive, is simple to use, and seems to work correctly. I have a high end calibrated source for my older meter, and when I tried it on the Extech it read exactly the correct value. So in a static situation the meter is very accurate. While I don't have any method to try it for peak or average readings, I'm guessing that it's probably beautiful darn close. I plan on using this for measuring machine noise levels, and also for monitoring sound levels for the PA for a jazz band I play in. If you need a DB meter, this one will do a amazing job at a amazing price.

I'm a long time sound meter user, for the purpose of setting up a Home Theater listening system of fifteen plus fore "upgrading" to this unit, I was using a Radio Shack, digital sound meter, the standard on a lot of Home Theater forums. I wanted better because like most, better is, well, just better; security in knowing you're using er beware: this is not a spec'd sound level meter. There are four types of sound meters; lab grade type 0, field/lab grade Type 1, professional general field use Type 2 and the unspecified Type 3 with the lowest calibration standards for general survey work to see if one needs a better quality sound meter. This unit qualifies as a Type 3 as there's no mention in the provided data sheet of this unit being of any type. This is very necessary if one is going buy and use this unit for needed spec'd measurements such as OSHA, lab, legal or law enforcement.Overall, my first impressions were, how light it was. Yes, I'm human and I like my gear to have some heft to it. Along with this sound meter, I purchased a sound meter calibrator. Beware, the first thing I did when calibrating this unit, I pushed the side mounted calibration wheel into the casing and had to take the case apart to "bend" the potentiometer, back into place. Not a amazing sign. The adjustment feature needs to be better secured as I'm a careful user of gear and from my experience, this shouldn't have happened. It's fixed, you've been warned, life is ing forward, the meter reading is what I would characterize as unstable (even on slow, the readings flicker too much) and with a noise threshold of >40dB, does not go low enough for in room measurements. The Radio Shack, digital sound meter is limited to >50dB and yes, at >40dB, this unit is an improvement but at
