The  Acoustic calibrator for mobile use / For different weighting filters / Accuracy IEC 942, class 1 / For microphones with different dimensions, Equipment that performs the calibration and ensures the proper functioning of a sound level meter. The Acoustic Calibrator is a battery powered sound source. With this acoustic calibrator, you can quickly and directly calibrate a sound level meter and other systems. Acoustic Calibrator Adapters allow you to connect and control 1.5-inch and ¼-inch microphones. The calibration frequency used by this acoustic calibrator is 1000 Hz. This is the reference frequency for international standard weighting curves. Thanks to this you can use this acoustic calibrator to calibrate sound level meters with A, B, C or D weighting filters. The calibration pressure of the acoustic calibrator is 94 ±0.3 dB (1 Pa) and 114 ±0.3 dB (10 Pa). Thanks to this, you can use the acoustic calibrator, for example, in quality control to check and even calibrate a sound level meter.
