How to distinguish between catalytic and infrared combustible gas detectors
Infrared versions are more stable, offer higher precision, have a longer lifespan, but are more expensive. . . . . . . . Feel free to contact me if needed
I want to know how to tell the difference. Please advise, thank you
In actual production processes, the commonly used detectors for combustible gases and toxic gases include catalytic combustion detectors, heat conduction detectors, infrared gas detectors, semiconductor detectors, electrochemical detectors, photoionization detectors, etc. Therefore, the requirements regarding the selection of detectors for combustible gases and toxic gases in these regulations are also based on these commonly used gas detectors. For other special types of gas detectors, such as polymer gas sensors and open-circuit infrared gas detectors, their selection and scope of application should be determined in accordance with the requirements specified in the product’s technical documentation.

But how can we tell the difference? ? Solve
But the appearance of the instrument and its display screen can be changed, and especially the probe can be replaced. I want to know how to distinguish them fundamentally
Look at the sensors; the P sensor looks different
It’s easy to tell just by looking at their appearance: those of catalytic combustion or electrochemical type are about as long as pressure transmitters, while infrared types resemble cameras in size. The detection principles of the two are fundamentally different. In the petrochemical industry, infrared technology is not widely used and has a poor reputation; if the existing products were truly as effective as claimed, their market share would not be so low.
Thank you, but what I want to ask is how to prove it
Thank you. Do you mean that all those available on the market now use catalytic combustion? But as far as I know, there’s more regarding infrared
