PCE-SC 43 Class II Acoustic Calibrator

Acoustic calibrator with different sound pressure levels / Accuracy ±0.4 dB / Frequency: 1000 Hz for A, B, C and D frequency weightings / 1/2″ microphone opening / Battery operated / Class 2

The calibration frequency used by this acoustic calibrator is 1000 Hz with sine wave. Compared to other calibrators, this acoustic calibrator has three different reference levels: 94 dB, 104 dB and 114 dB. Just press a button to change the reference level. This acoustic calibrator, unlike other calibrators, has an additional reference level of 104 dB. This acoustic calibrator works with an accuracy of ±0.4 dB. Thanks to this, it is possible to check the accuracy of sound level meters and, if necessary, to adjust them. You can optionally request a calibration certificate for the acoustic calibrator.

The acoustic calibrator works with 2 x 1.5 V batteries (type AA) with an autonomy of approximately 50 hours. Built-in auto-shutdown causes the acoustic calibrator to turn off after 20 minutes of inactivity.
