Description

The Cirrus Research Low-Cost Integrating Decibel Meter

The CR:310 is an integrating decibel meter ideal for simple noise measurements and basic noise at-work measurements. In addition to measuring the maximum sound level (LMax), CPeak, and the sound pressure level (SPL), the CR:310 provides average noise level data (Leq) and the overall dose values (Leq8h), this allows it to be used for basic workplace noise assessments.

The decibel meter also displays A and C frequency weightings, as well as Fast and Slow time weightings which other basic sound level meters available on the market cannot. The CR:310 displays the Leq for one measurement, using the start/stop button on the instrument. You can also send the measurements directly to a portable printer (sold separately).
