For Occupational Noise and Industrial Hygiene, measuring the noise exposure of employees quickly and reliably is essential.

The optimus red sound level meters are the ideal instrument with a clear, high resolution OLED colour screen, a wide 120dB measurement span and simultaneous measurement of all parameters.

The CK:690 is a weather protected outdoor kit that is designed for use with the optimus green sound level meters.

The kit allows the optimus to be used outdoors over long periods of time and in all weather conditions.
