Great features and great value
I was looking for a sound meter for setting up my surround sound system. dB-C weighting was important, as this covers the whole audible sound spectrum, allowing my subwoofer to be measured (dB-A weighting, rolls off in the upper bass).This unit has dB-A and dB-C weighting, so the best of both worlds. Fast and slow "polling" is also selectable. Slow averages the reading over a 1 second period, which helps reduce the reading from bouncing around.The unit can be connected to a computer to collect the readings (and monitor the readings) but I haven't tried this. This would be good for setting up a sweep tone and plotting the sound levels across the sweep. I may try this later.Display is large and clear and buttons are positive. Backlight works well but the display is adequate without it in normal light.For my purpose, setting up speakers to output the same level at the listening position, this is more than adequate. The tripod screw socket is also a nice touch. It also comes with a zip-up cloth case.

Nice tool
A nice and easy to use tool at a reasonable price. It is easy to start using it and the manual is clear.Have already recorded two samples after 10 minutes of use and have saved the recording results on my computer.

Fine for long duration sounds, Don't bother with the record functionality
Bought this for the record/datalogging functionality however I'm sending it back after about 10 minutes of use.The datalogging function is pretty much useless unfortunately. In order to record, the record parameters must be configured before each recording. This means you need to connect it to the software and reconfigure the recording if you need to do more than one recording.Another issue is the minimum interval between data points is 1s. Software will not let you go less than 1s.This does not work with windows 11 due to driver issues, it does not find the sound meter. On windows 10 it works fine.The screen itself only refreshes every 0.5s on fast mode so it is realistically no use for short bursts of sound even if the supposed sample rate is 125ms.I have no way of verifying how accurate the sound meter is.
