Get PriceTwo common technologies for detecting combustible gas are IR and catalytic bead (pellistor) detectors. An IR gas detector responds to gases that absorb IR radiation, such as hydrocarbon-based methane and propane. But since hydrogen cannot absorb IR radiation, IR gas detectors will not detect hydrogen and therefore are not recommended.

Get PriceThe IR5500 is an open path infrared (IR) gas detector that continuously monitors for flammable gas leaks over large open areas. It monitors in both the LEL-m and ppm-m ranges to detect both small and large leaks. The IR5500 offers the benefits of early detection with its high sensitivity to gas concentrations at the ppm levels.
Get PriceThe sample is drawn through the Gastec glass tube, which is filled with a chemical reagent that absorbs and reacts with the target gas/vapour. This creates a colour change which can be measured by reading the concentration marked on the tube. They are ideal for short term measurement and low level detection.
Get PriceWhen it comes to lifesaving gas detectors, you can't afford to guess. Gas detectors today offer features that provide clear information on the instrument status and sensors, tell the user how to react when an alarm goes off, and make it easy to interpret the readings. This white paper covers technology that makes gas detection easy for all users.
