AIHCE show at Atlanta, May 10 to 12

Casella USA do it again. Two new sound level meters are added to the popular CEL-400 series of noise instruments. The CEL-450 and CEL-490 are developed versions of the CEL-440 and CEL-480 units and feature an all new design using the computing power of the latest DSP chips. DSP or Digital Signal Processing has been used in more expensive hand held instruments such as the CEL-500 series before but now finds its use in these two new models.

Careful design of the analog circuitry in the meters result in an incredible 140 dB dynamic range! This means that there is no need to worry about selecting the best range since the meter is always on the right range. No more worries about overloads or under range signals as the new design covers all audible sound from 0 right up to 140 dB in one single setting.

The other key feature is the provision of real time octave or third octave filters giving a 10 or 30 times increase in the speed of measurements when compared to the older type of serial filters employed by other meters at these prices. This will speed up the collection of recordings for the busy hygienist for OSHA compliance surveys. Data capture as fast as 100 spectra per second enable fast transient noises to be frequency analyzed correctly in one measurement.

Two key models are available with the CEL-450 aimed at the industrial hygiene market and the expanded CEL-490 model finding use in longer term environmental monitoring. Models complying with both ANSI type 1 and type 2 are available with a choice of sound level meter broadband only or broad band and octaves or third octaves.

A companion Windows software package called dB23 comes with each of the kits providing download to a personal computer running the popular MS Windows operating system. Kits are  provided with all the items needed to make high quality noise measurements at a remarkable low cost.
