Cirrus crl 254 integrating sound level meter

For industrial noise assessment etc
This unit is ex MOD and is in excellent condition.
As an integrating sound level meter it will work out the average exposure (Leq) from the varying noise levels experienced during noise monitoring tests and this Leq figure can be added to the noise exposure calculator provided by HSE for daily noise exposure calculations.
It is not the latest meter and is not currently calibrated but I have checked the indicated sound levels with a noise meter calibrator and the readings were spot on at the 94dB and 104dB signals.
The meter comes with full instructions for use which are easy reading and very helpful and informative for taking noise measurement readings.
Aquisition Range: Typically 75 to 135dB
Functions: Leq and Sound Level (SPL)
Indicators: Red (LOW BAT), Green (STOP),
Batteries: 2 off 6F22 9Volt supplied
Battery Life: 16 hours intermittent use
Weight: 460 gms including batteries
