SV 33A

SV 33A

The SV 33 Class 1 Acoustic Calibrator produces acoustic pressure with a specific level of 114 dB at a frequency of 1 kHz. The SV 33 is suitable for the calibration of Class 1 and Class 2 sound level meters as well as dosimeters with 1/2 microphone.

Unlike other calibrators, Svantek calibrators feature a sturdy housing that provides a comfortable, secure grip for the user. The interior design of our acoustic calibrator is based on a reference microphone and a microprocessor controlled signal source including digital static pressure and temperature compensation.

Due to the feedback regulation control loop, our calibrator does not require any adjustment by the user and operates over a wide range of ambient temperature and humidity to ensure excellent stability of its calibration level and frequency. Each acoustic calibrator comes with a calibration statement that allows users to be confident that their instrument will measure correctly.
