Testing and Calibration of Fixed Gas Detector Heads
Introduction
In order to ensure the safe and accurate operation of Fixed Gas Detectors, they need to be periodically calibrated against reference test gases that are traceable to National Physical Laboratory standards. The recommended calibration period for Status Scientific Controls gas detectors is six months although the frequency may need to be increased where continual exposure to the target gases is experienced.
Between calibrations it is also recommended that the response of the detector is checked using an appropriate test gas cylinder. These cylinders are available in 'large aerosol' form and may be supplied individually or as part of a Field Calibration Kit.
Status Scientific Controls offers a range of support equipment, including compressed gases, for the customer to carry out both calibration and response testing of Fixed Gas Detectors.
