Acoustic Calibrator AC 300

Precision acoustic calibrator AC-300 for sound level meter calibration

The AC-300 acoustic calibrator is a practical and precise device for calibrating sound level meters. The microphone of the sound level meter is inserted into the acoustic calibrator. The acoustic calibrator will then emit a signal of 250 Hz or 1000 Hz (user-selectable) with a sound level of 114 dB. This allows for quick and easy calibration. The acoustic calibrator complies with the standards for calibrating sound level meters IEC 60942 (2003-01). To save battery energy, it has an automatic shut-off function. If the battery level is low, a warning will appear on the screen.
