The calibrators used for the sound level meters can provide a quick and precise field calibration. The 2 main brands of caibrators carried by Pine are Quest and Casella. 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, whereas the QC-20 is recommended for use with IEC Type 1 meters and has user –selectable frequencies of 94 or 114 dB and 250 or 1,000 Hz frequencies. 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.

Quest models QC10- and QC20 are accurate electroacoustic calibrators that generate a stable acoustic signal at a controlled frequency and aamplitude level. Their principal use is for a calibration accuracy check of sound level meters and oise dosimeters. Other acoustic analyzers, such as FFT or Real Time Spectrum annalyzers, hearing aid test instruments, or other audio systems utilizing a microphone for input signals, may be calibrated with the QC-10 and QC-20.
