Certifiable Calibration - Castle group dBAir Operating Manual

Certifiable Calibration

The calibration process includes the microphone, pre-amplifier and sound level meter.
Any change in this measurement chain will require a new calibration certificate.
Castle Group Ltd offers a complete calibration service offering either a full UKAS
calibration or a standard traceable calibration which can be supplied with or without a
test report.
It is recommended that your sound meter instrumentation is calibrated annually to
ensure your measuring equipment is completely accurate and fully compliant.
