The acoustic calibrator provides quick, precise field calibration. The calibrator generates a constant sound pressure level of 114 dB at a fixed frequency of 1,000 Hz to verify the accuracy of the meter in the field. Adapters available for all SGS Galson sound level meters and noise dosimeters.
* Included at no charge if requested with noise dosimeter 5-packs.
