Compact, Affordable Performance

Cel200.jpg (6109 bytes) The CEL-200 series sound level meter is an affordably priced instrument for noise checks in the workplace or for general noise measurements.  The CEL-231 is a digital sound level meter that will appeal to anyone new to noise measurement.  Simple to use and understand, Model 231 is for spot checks of steady noise levels.  It measures in dBA, which most closely represents the way human hearing reacts to noise.  Model 254 adds a C frequency weighting, impulse time weighting and a maximum hold feature.
