Noise level carefully measured at workplace

Cirrus Research's new sound level meter includes automatic recording option.

The CR:262 sound level meter from Cirrus Research enables employers to comply with the latest Noise at Work Regulations.

The instrument is categorised as 'Integrating Averaging Class 2' for Type 2 Broadband Measurements in the 26 - 140dB range.

The applications include: Assessment of noise in the workplace; Measurement of environmental noise; General purpose noise measurements and assessments; Selection of hearing protection.

It provides safety officers with an accurate measurement tool that is easy to use and requires no set-up procedure, user training or reference to an operating manual prior to use.

It simplifies the procedure of providing up-to-date noise measurements and risk assessments as required by current legislation.

The hand-held instrument weighs only 450 grammes and has only three pushbuttons to calibrate, start and stop measurements.

This makes it an ideal portable tool for use in the working environment, including outdoors, typically for track or roadside locations where there is a need to record the sound levels of passing trains or vehicles.

After initial calibration and selection of measurement range, the user can select either numerical or graphical screen displays.

During measurement, all current parameters with a quasi-analogue bar graph representing the current sound level are shown on screen.

On completion of measurement, all of the parameters can be viewed at the same time.

The final measurement is also stored, and automatically displayed when the instrument is next switched on.

The CR:262 can also be upgraded to the +Version which includes additional functions and features including: Up to 100 measurements stored in memory with 1 sec time history Measurements download to PC for use with latest version of Deaf Defier 3 software to facilitate analysis and reporting.

The instrument upgrade can be carried out by the user after purchase of a unique key which unlocks the full range of additional functions available.

The CR:262 can be supplied as a stand-alone sound level meter, or incorporated into a measurement kit comprising meter, acoustic calibrator, windshield and carrying case.
