Larson Davis Cal150 Acoustic Calibrator - Acoustic calibrator with 2nd class accuracy 94/114 dB, 1 kHz

Larson Davis Cal150 Acoustic Calibrator - The Cal150 is an acoustic calibrator with 2nd class accuracy suitable for calibrating 1/2" microphones at 1000 Hz frequency. The device operates on battery and can output sound pressure levels of 94.0 or 114.0 dB, switchable. Due to its design, it can be used for both laboratory and on-site calibrations.

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