Cirrus Research CR310 Integrating Sound Level Meter

The Cirrus Research CR310 Integrating Sound Level Meter is the ideal tool too provide noise measurement data whilst performing basic noise work place assessments. The integrated sound level meter with a ½ pre-polarised elecret condenser microphone provides users with the ability to measure noise level data (Leq) and the overall dose values (LEq8hy) with accurate and reliable measurements that meet IEC 61672-1:2013 Class 2 standards.

The CR310 provide sound pressure (SPL), maximum sound level (Lmax) and Cpeak data whilst displaying A and C frequency weightings with measurement ranges of 30dB (A) to 130 dB (A) and 40 dB (C) to 130 dB (C). Further functions include the measuring of Fast (F) and Slow (S) time weightings, providing users with the perfect tool to complete a number of applications such as general noise surveys, alarm installation and testing and machinery noise checks.
