Class Class 2
Available Outside the UK? Yes
Most Measurement codes of practice and good practice demand that an independent acoustic calibration of any sound level meter should be made before and after a series of measurements and the Castle GA601 provides just that facility. It produces a calibration tone of 1000Hz at a level of 94dB re 20µPa at the microphone. It is supplied with a ½" cavity. The GA601 calibrator provides an accurate, stable and simple to use sound source for carrying out the acoustic calibration of a wide range of sound level meters. Producing two levels, 94dB and 104dB, this Class 1 Acoustic Calibrator was designed and has proven to be rugged and long lasting. The calibrator is switch operated, which engages the selected sound source for one minute, after which it automatically turns off. The GA601 is designed for use with Castle Sound Level Meters as well as a variety of other brands which feature a nominal half inch microphone capsule.
