ADD358 Digital Sound Level Meter
This handheld sound level meter is very easy to use, just switch it on, set the range and start measuring. The wide 40-130dB range (120dB is pain threshold!) makes it useful for many situations including noise pollution monitoring, home theatre setup, health and safety compliance, vehicle noise testing etc.
In particular it meets the LTSA requirements for the 'Noise Quick Check' (when combined with the sound meter calibrator). It comes in a foam lined plastic case with compartments for the windscreen sponge and spare battery.
The meter is supplied ready calibrated. If you need to verify the meter readings it can be done (and re-calibrated if necessary) with the Sound Level Meter Calibrator 94dB SC941.SPECIFICATIONS
