CPS Combustible Gas Detector Combustible and flammable gas detectors sense the presence of one or more gases near the detector.
For dangerous gases, gas detectors will have audible and visible alarms. Fixed mount units would include relays to trip equipment, close valves, etc. to return to safe conditions.
Today’s gas detectors can have multiple gas detectors for detection of several gases. Knowledge of the application and desired gases is key in model selection.
Frequent calibration is also important. Gas detectors drift, so most manufacturers recommend monthly calibrations or at least calibration checks. Make sure to read and follow the manufacturer instructions with each instrument.
