Sound Level Meters are handheld devices, which can be used for workplace noise or environmental surveys.
Casella's entry level CEL-240 series is an easy-to-use instrument designed to undertake noise measurements for a variety of applications. By implementing the latest digital technology, the CEL-240 gives absolute reliability, ensuring the highest levels of accuracy and performance, all housed in a rugged and compact design. With the graphical display the CEL-240 can display the time-history of noise levels, allowing an easy assessment of the current noise environment.
Models are available to measure just the cumulative noise (CEL-620) such as average and peak levels for workplace noise, where octave band (B versions) can be used for the selection of hearing protection. The CEL-630 series features time history storage and parameters for environmental noise (CEL-633) and also have 1/3 octave band analysis (C versions).
