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/check gas cylinder. These cylinders are available in both small and large aerosol form and can be purchased from specialist test gas suppliers such as Specialty Gases (http://www.specialty-gases.com) and Calgaz (https://www.calgaz.com).
110 Litre Test Gas Large Aerosol Cylinder
(See above for examples of suppliers)
110 Litre Cylinder Flow Regulator

Status Scientific Controls offers a range of product calibration equipment for the customer to carry out both calibration and response testing of Fixed Gas Detectors.
