The 3M model QC-10 calibrator provides quick, precise field calibration. The calibrator generates a stable acoustic signal at a controlled frequency and amplitude to verify the accuracy of your meter in the field.

The model QC-10 is a general purpose calibrator that generates a constant sound pressure level of 114 dB at a fixed frequency of 1,000 Hz.

The QC-10 has a standard one-inch coupler opening that may be reduced by inserting available snap-in adapters. The calibrator also provides a precise 1-volt RMS output signal via a 1/8 inch phone jack to check devices.
