The CEL-630 Sound Level Meter from Casella CEL simplifies the task of measuring workplace and environmental noise. It provides the operator with simultaneous overall average decibel level results along with a time history record of the noise level with one-second resolution, as well as a frequency breakdown (spectrum) to further quantify specific noise hazards.
