Larson Davis Cal200 Acoustic Calibrator - Acoustic calibrator of Class 1 accuracy 94/114 dB, 1 kHz

Larson Davis Cal200 Acoustic Calibrator - The Cal200 acoustic calibrator of Class 1 accuracy is suitable for calibrating 1/2" microphones at 1000 Hz frequency. The device operates on batteries and generates (switchable) sound pressure levels of 94.0 or 114.0 dB. Due to its design, it can be used for both laboratory and on-site calibrations.

Its calibration traceable to NIST ensures accuracy. The sound pressure it provides is independent of the battery status. It can be used for calibrating sound level meters, noise dosimeters, and noise monitoring stations.
