The battery operated Precision Calibrator is tailored for the calibration of sound level meters and other sound measurement equipment. It can provide an output level of either 94.0 or 114.0 dB (switch-selectable) at a frequency of 1 kHz.
It has been designed for both field and laboratory use and the accuracy has been calibrated to a reference traceable to the National Institute of Standards and Technology (NIST).
The Precision Calibrator features a stable sound pressure independent of the battery condition. It will turn off automatically to preserve battery and guarantee a stable output.
