Digital noise sound meter decibel AR824 30-130 db fedex
Essential for measuring and maintaining noise levels in the work place to comply with regulations and for checking the acoustics of auditoriums, studios and home theatres, this 4 range hand-held sound level meter has an easy to read indicator and is battery operated for true portability.
The meter has been designed to IEC 651 TYPE2 and ANSI S1.4 TYPE2 for sound level meters and gives an instantaneous measurement reading between 30dB and 130dB.
Features include the ability to change between the fast and slow settings with the flick of a switch to monitor either an average or the peak sound levels present in the environment and A and C weighting for the measurement of different levels. A covers general sound level measurements whilst C is for checking the low frequency content of noise.
