The battery-operated Class 2 Sound Calibrator is classified for the calibration of class 2 measurement microphones, sound level meters and other acoustic measurement equipment. This microphone calibrator delivers 114 dB at a frequency of 1 kHz.

The MA220 and MA230 offer a low noise microphone preamplifier compatible with standardized 1/2″ microphone capsules. Both include an electronic datasheet for fast setup and ensuring accurate measurements. The MA230 is additionaly enabled for periodic self-tests (Charge Injection Check CIC) dedicated for permanent noise monitoring stations.

The battery-operated Class 1 Sound Calibrator is classified for the calibration of class 1 measurement microphones, sound level meters and other acoustic measurement equipment. This precision microphone calibrator delivers 94 or 114 dB at a frequency of 1 kHz.

The Dehumidifier protects the microphone capsule from possible water damage caused by condensation due to high humidity. This provides reliable and precise measurements in changing environmental conditions. The Dehumidifier is an accessory for the outdoor measurement microphone M2230-WP (= M2230 with WP30) and M2340-WP (= M2340 with WP30).

The calibration certificate lists the individual product data with serial number. The calibration and adjustment procedures follow the documentation and traceability requirements of the EN ISO / IEC 17025 standard.
