    • Good product, careful about what’s next to the switch
Style: Standard
Consistent product. Holds up great while being on tour, stays consistent. The only gripe i have is when it’s in my bookbag or pelican, the switch to generate noise activates sometimes.

    • Reed Instruments R8090 Sound Level Calibration - Very fast delivery and excellent quality
Style: Standard
I ordered it last Jan 30, 2024 from the U.S.A and it was delivered at my residence here in the Philippines yesterday (Feb 5). I tested it and its working well. The seller is HIGHLY recommended. Thank you very much

    • It does what it's suppose to do.
Style: Standard
If you care about using a calibrated sound meter, you'll need one of these. The unit has no whistles or bells. It has an on switch that allows you to set the unit for either 94dB or 114dB @ 1kHz. More can be found at reedinstruments.com under the heading; safety > sound meter. The unit is designed to calibrate sound meters with a 1/2" diameter microphone shaft. I found this unit to be the least expensive calibration unit I could find as all the other calibrators were in the $250.00 price range. I gave it five stars because it works and can be had for the best delivered price I could find and this was after a couple of days of web surfing. I can recommend this product for those two reasons and based on personal experience, it does what it's suppose to do. I'm a happy camper. I know this review is brief but there's not much that can be said about a no whistle-and-bell type product of this kind. It works and it's the best delivered price I could find. If that's what you're wanting, a best price device in which to check the calibration of your sound meter that has a 1/2" microphone column, this product will do what you're wanting. Hope the above helps in your buying decision. ... show more

    • Solid choice.
Style: Standard
Great device! Make sure it is the right size for your mic. I just wish it was harder to turn on while traveling in my gig bag. I have on a few occasions found it accidentally got bumped on.

    • For the price, this device is unbeatable!
Style: Standard
I've used expensive calibrators and my experience is that this one works as well as any. For legal work one should get a cal certificate from B&K or NIST or some other recognized entity, yet all my SPL meters are within a fraction of a dB of each other. Re: environmental noise, who cares about a half dB or so? I'm open to be educated on this. ... show more

    • Simple to use and accurate
Style: Standard
I used this Reed 8090 to track accuracy of an inexpensive BAFX3608 sound meter and the reed works flawlessly every time and is super easy to use. Perfect for quickly checking calibration before every measurement session!
