Colour is a sound solution
July 21st 2008 Manufacturer of environmental monitoring equipment, Casella, 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 620 series of pocket sized meters which incorporate a high resolution colour display into a small and easy to use sound level meter.
According to Casella its 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 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.
