Combustible gas detector inspection
Thread Content
What gas is used for calibrating the probes of combustible gas detectors? What gas is used for calibrating the probes of toxic gas detectors? (Ethylene oxide) Are these gas samples available on the market?
Aren’t you hiring a third party to do this? Do you plan to conduct the inspection yourselves? The flammable substance is in the methane gas cylinder, with the concentration prepared by a third party. I don’t know about those that are toxic.
For fuel, methane gas can be used; for EO, CO can be used. This can be asked to the manufacturers of gas detectors……
Does the manufacturer have to provide sample gas when selling detectors for our daily maintenance and calibration?

It depends on whether you request standard gases when purchasing a combustible and toxic gas detector; if not, they are generally not included.
Gases such as methane in combustible gases fall under the category of instruments that require mandatory calibration; you need to submit them to the regulatory authority for inspection. If it’s another type of combustible gas, then a third party is required to carry out the calibration. If you establish your own standards and obtain authorization from the local authorities, you can conduct the calibration yourself as well. Generally, methane is used as a reference for calibration, but the calculation must be adjusted according to the actual gas being tested, as their lower explosion limits vary.
Although we also have third-party testing, during regular production we conduct periodic checks to ensure that everything is in good condition, so that any issues can be identified and repaired or replaced in advance.
That is, what do we need to prepare during regular inspection and maintenance procedures?
