The GA607 meets the demanding standards of a Class 1 calibrator. It
features two calibration levels, 94dB and 104dB re 20µPa both at 1kHz
and is supplied with required barometer. It is for use with ½”
microphones. This GA607 Acoustic Calibrator comes with a 12 Month
Manufacturers Calibration with Certificate.
Using the GA607, a sound level meter can be checked at two meter scale points and usually on two ranges. IEC 60942 states that for a calibrator to be used in the Class 1 category, it must be corrected for barometric pressure. That's why the Castle GA690 barometer is supplied with the GA607 Class 1/C calibrator for just this purpose. With a simple readout on the clear display and a correction table printed on the reverse, this is a very simple process.

Castle GA601 Single Level Class 2 Sound Meter Calibrator
|
The Castle GA601 produces a calibration tone of 1000Hz at a level of 94dB re 20µPa at the microphone.

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.
