Castle GA611 dBCal Class 1 Triple Level Acoustic Calibrator
The Castle GA611 dBCal Class 1 Triple Level Acoustic Calibrator is a sound level calibrator providing three output levels (94dB, 104dB and 114dB) ah 1kHz, to ensure the acoustic field calibration of the sound meter is accurate before and after measurements and offering greater options for testing sound meters.
The GA611 uses 'line of sight' ergonomics showing all controls and displays on the same surface as the sound meter being tested.
When testing a wireless sound level meter, the Cable GA611 can automatically pair withb the meter every time a calibration is performed. A calibration report can be generated with information such as serial number of the meter tested and calibration status on the calibrator and the sound meter. Using the Castle Cloud software, users are able upload and store reports allowing a traceable and secure calibration history.
The Castle GA611 has a 1/2” cavity in which to insert a Class 1 sound level meter microphone and allows for MEMS microphone feedback for atmospheric pressure compensation with a range of 65kPAa to 108kPa.
The Castle GA611 has the specification to meet the exacting requirements of Class 1 calibration and meets industry standards EC 60942:2017, BS EN IEC 60942:2018, ANSI S1.40 2006 and is hand held with a battery life of up to 70 hours continuous use.
