Noise at Work

This sound level meter is the correct specification for all noise at work assessments being carried out in line with the EU regulations and the UK HSE guidelines. These regulations demand the use of an integrating sound level meter that meets IEC 61672 standard to Class 2. The meter is capable of measuring LAeq and LCpeak.

The meter also measures the C weighted Leq (LCeq), which can be used for a basic hearing protector assessment - checking that the level at the ear is reduced adequately. For a more detailed hearing protector assessment with the assistance of software please see the CK162C Optimus Red meter.

General Purpose Noise Measurement

The Optimus Red is suitable for any general purpose noise measurement that demands the use of a Class 2 Sound Level Meter or Class 2 Integrating Sound Level Meter.

If your measurement guidelines don't mention standards then this meter should also be adequate, but please check with us first if you have any doubts.

Calibrate

The noise at work regulations state that the meter's calibration should be checked before and after making measurements.

Put the Calibrator on the mic. and select the Calibrate option.

Keep a record of all calibrations to meet the noise regulations.

Measure
