CR:303 Sound Level Meter

The CR:303 is a simple, robust Sound Level Meter designed for applications where a quick check of the noise levels is required. The instrument displays Fast Sound Level in dB(A) and has a measurement range of 35dB(A) to 135dB(A). A maximum hold function is also provided to hold the highest reading that the instrument displays. As the CR:303 does not provide measurement of Leq or Peak(C), it is not suitable for compliance with Noise at Work Regulations in the EU, but is ideal for simple checks and assessments.

The CR:303 uses a standard 1/2" microphone capsule and therefore is compatible with the standard Cirrus Research plc Acoustic Calibrators such as the CR:513A.

A range of accessories is available for the CR:303 including windshields and carrying cases. The instrument is also available as a measurement kit
