Features:
- Class 1 calibrator
- 3 output levels, 4dB, 104dB & 114dB, each at 1 kHz. This allows greater options for testing sound meter
- Line-of-sight ergonomics: all controls and displays on same surface as sound meter
- Simple operation: turn on and go!
- Ultra-low distortion and stability
- MEMS microphone feedback for atmospheric pressure compensation.
- Compliant with 2018 standard
- User-upgradable software for future-proofing
Calibration Reports:
For wireless sound level meters, such as the Castle dBAir, the calibrator (GA611W) and sound meter can automatically pair each time a calibration is performed, generating a calibration report containing the serial number and calibration status of the calibrator as well as that of the sound meter. This report will be stored within the sound level meter and later uploaded to the Castle Cloud software, in order to create a traceable and secure calibration history database.
