    Castle GA690 Electronic Barometer

    The Castle GA690 Electronic Barometer is designed for use with Castle GA601 and GA607 Sound Level Calibrators. It is particularly useful for Class 1 sound level calibration as meters must be corrected for atmospheric pressure during calibration, thus requiring accurate atmospheric pressure measurement.

    The Castle GA690 measures atmospheric pressure from 0 to 1300mbar (0 to 975mmHg) with resolution of 1mbar and accuracy of ±0.25%. Readings are shown on the clear digital display and operation is carried out using just three buttons. A correction table is printed on the back of the instrument to aid atmospheric correction in sound level calibration.

    Castle part number: GA690
