The Quest Technologies model QC-10 and QC-20 calibrators provide 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 model QC-20 is recommended for use with precision ANSI and IEC Type 1 meters. User-selectable 94 or 114 dB and 250 or 1,000 Hz frequencies generate four different outputs.
Both models have a standard one-inch coupler opening that may be reduced by inserting available snap-in adapters. The calibrators also provide a precise 1-volt RMS output signal via a 1/8 inch phone jack to check devices such as the Quest VI-90 Vibration Integrator.
