Colouring Sound Level Readings

Aug 26 2008 Read 1027 Times

Casella a UK manufacturer of environmental monitoring equipment has developed a colour-coded display system for sound level meters which simplifies their use and reduces the risk of misinterpreting data. Casella CEL has now launched the all new 620 series of pocket sized meters which incorporate the high resolution colour display into the smallest and easiest to use sound level meter on the market.

The Casella CEL-620 series is now the smallest octave band analyser in the world, and probably the strongest too. The colour readout assists the user by displaying results in a simple colour coded format that is impossible to misinterpret. Ease of use has been a key design goal in the development of this instrument, so from simple point and shoot measurements to full industrial hygiene assessments, all measurements can be performed quickly and easily.

This is industrial equipment and was designed with an overmoulded case to give it the strength and durability needed for tough industrial environments. The CEL-620 uses all digital technology that can measure in a range up to 140dB, dismissing the need for range adjustment and eliminating reading errors which may result. Another unique feature is that it measures all occupational noise parameters simultaneously; rather than changing the instrument setup you simply change which noise parameters you wish to view knowing that all parameters can be viewed afterwards even if not selected at the time.

"The CEL-620 really presents the next generation of workplace sound level meters," said Tim Turney, Product Manager for Casella CEL. "A real-time octave band analyser has never been so compact and yet filled with technology designed to make life easier for the health and safety professional."

The CEL-620 is supplied as a kit in a rugged briefcase, which also includes an acoustic calibrator, windshield, software and USB download cable. Both instrument and calibrators come with calibration certificates as standard, documenting compliance with the latest IEC 61672 Sound Level Meter standard.
