Review on π RISEPRO Decibel Meter, Digital Sound Level Meter 30 β 130 dB Audio Noise Measure Device with Backlight, MAX/MIN, Data Hold, Auto Power Off, and Dual Ranges - HT-80A by Jay Maryland
Totally inaccurate rubbish
First off it's advertised as a minimum of 30dB but if you read the manual it clearly says 40dB to 130dB. This meter reads 60 dB in a dead quiet room. When you turn on the backlight, the reading drops by 20 dB. Regardless of the reading, the backlight goes out as soon as it is turned on. Someone bought 2 and put them side by side and they were off by 30dB when measuring the same thing. It's worse than toys.
- Great construction
- Weight
