Application

Application of Professional 8930 AZ Noise Tester Calibrator:
The compact 8930 AZ Sound Level Meter Calibrator
is a portable, battery operated sound source, suitable for many portable sound level meters.

When a microphone from a sound level meter is inserted into this calibrator, the sound level meter picks up the signal and displays the signal in dB (decibel) units. The sound level meter should be adjusted (if necessary) to match the calibrator's output signal as closely as possible.


The generated sound pressure level is equal to 94dB, 104dB and 114 dB at 1000 Hz frequency. The 1000 Hz frequency allows calibrating sound level meters with any frequency weighting (LIN, A, B, ...), Without applying any correction factor. 
It can be conveniently used both in laboratory and in the field. The 114 dB sound level allows performing calibrations even in high background noise environments.

There are total 4 models allow calibrating different size microphones with mechanical dimensions compliant with IEC 61094-1and IEC 61094-4.

The Digital 8930 AZ Sound Level Meter Calibrator was being designed and manufactured by AZ Instrument, a well experienced manufacturer for Environmental Measuring Instrument.
