Description
The 8930 AZ Sound Level Meter Calibrator provides reliable and portable calibration for sound level meters. Compliant with IEC 60942:2018 Type 2, it delivers accurate sound pressure levels in laboratory or field environments.
Built for stability, the 8930 remains accurate under varying humidity, temperature, and air pressure, making it suitable for high-altitude or challenging conditions.
Key Features
- IEC 60942:2018 Type 2 compliant
- Three calibration levels: 94 dB, 104 dB, 114 dB at 1 kHz
- Compatible with AZ sound level meters (8921, 8922, 8925, 8928)
- Works with microphones compliant with IEC 61094-1 and IEC 61094-4
- LED indicators for output level, stability, and battery status
-
Portable and battery-powered (50 hours typical use)
Applications
- Accurate calibration of sound level meters in labs or in the field
- Reliable operation in high background noise environments
- Compatible with any frequency weighting (LIN, A, B) at 1 kHz
When a sound level meter microphone is inserted into the calibrator, the device generates precise decibel readings that ensure accurate measurement.
