Gas Detector Calibration

Gas detector calibration keeps portable and fixed detectors reading accurately, so alarms trigger at the right gas levels and your site stays compliant. Regular calibration with certified calibration gas, plus bump testing between calibrations, is what makes a detector safe to rely on in confined spaces, on mine sites and in plant rooms. The detectors below are models we supply and calibrate, including the Crowcon range used across mining, oil and gas, construction and manufacturing.

For what calibration covers, turnaround and how to send a detector in, see our gas detector calibration service.
