Cirrus Research CR310 Integrating Sound Level Meter Kit

The Cirrus Research CR310 Integrating Sound Level Meter Kit includes the integrated sound level meter alongside an acoustic calibrator and kit case. The included calibrator allows the users to ensure their meter is always fully calibrated. Suitable for conducting routine noise level testing and basic noise at work measurements with the average noise level data (Leq) and the overall dose value (Leq8h), the CR310 is suitable for use in a number of further applications including machine maintenance and testing, noise ordinance surveys and fire alarm testing.

Simple and easy to use, the CR310 has a large backlit LCD display that shows clear readings including A and C frequency weightings, Time weightings Fast (F) and Slow (S) and Max and Speak whilst complying with IEC 61672 Class 2 standards. Display functions shown are sound level, maximum, minimum and C peak.

The CR310 provides sound pressure (SPL), maximum sound level (Lmax) and Speak data and the ½ pre-polarised elecret condenser microphone allows for measurement ranges of 30dB (A) to 130 dB (A) and 40 dB (C) to 130 dB (C) to be conducted.

The CR310 can be powered by 2 x AA batteries or 5V DC power via mini USB that allows for use for up to 24 hours.
