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.
