Class 1 Sound Calibrator 94 dB & 114 dB (SV 36)

SV 36 is a type approved sound calibrator meeting class 1 requirements in accordance to IEC 60942:2017. The calibrator is designed for calibration of class 1 sound level meters and class 2 sound level meters at 94 dB and 114 dB at frequency of 1 kHz.

The accuracy of the calibration signal is controlled by a built-in microprocessor and reference sensors:  piezoresistive sensor that monitors accuracy of the generated pressure level,  atmospheric pressure sensor and temperature sensor. The feedback regulation control loop makes all adjustments of the calibration signal fully automatic so users do not require any manual adjustments to the ambient temperature and static pressure levels.

The SV 36 Class 1 acoustic calibrator features an infrared sensor that detects microphone presence and turns on/off the calibrator automatically. The calibrator is powered by two LR03/AAA batteries. Each acoustic calibrator is provided with a statement of the calibration which allows the user to be certain that their instruments will measure correctly.
