Class I acoustic calibrator PCE-SC 09-ICA with ISO calibration certificate

The Acoustic Calibrator is a battery operated sound source. This acoustic calibrator directly and quickly calibrates a sound level meter and other systems. The Acoustic Calibrator adapters allow you to connect and control 1″, ½” and ¼” microphones.

The calibration frequency used by this Acoustic Calibrator is 1000 Hz. This is the reference frequency for the curves weighting pressure to the international standard. 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), which allows you to use it, for example,

– Sound pressure level: 94 and 114 dB
– A, B, C, D weighting filters
– Immediate use
– Accuracy class 1, IEC 942
– Simple to use
– Adapter for different types of microphone
– ISO calibration certificate included
