Is third-party calibration required for combustible gas detectors?
Thread Content
May I ask if combustible gas detectors need to be calibrated by a third-party agency? Our company’s logistics department has dozens of combustible gas detectors installed in the storage tanks. When the safety supervision agency came for an inspection, they asked us to provide calibration certificates for those detectors. We contacted the manufacturers of the detectors to have them perform the calibration, and a test report was issued. However, the safety supervision agency said that this report was not valid; they required a certificate issued by a third-party institution. But such third-party agencies are not specialized in this area either. It basically just involves paying some calibration fees. I wonder if anyone else has encountered such a situation? If so, how was it handled?
Contact the local metrology and inspection authority; this equipment falls under the category of devices that require mandatory inspection. It’s sufficient to have a mandatory inspection certificate issued by a metrology agency
The testing of combustible gas detectors is listed as an important item among various safety inspections. Our company has always entrusted the Municipal Metrology and Calibration Institute to carry out this testing, and it is the institute that issues the test reports – these reports are official, bearing a seal, and the probes come with certification labels as well.
If third-party verification is required, the certificate is generally issued by the local metrology bureau where the detector is used. The cost can be negotiated with the supplier.

It must be a third party; verification by the manufacturer does not count.
Then just have a third party conduct an inspection – that’s all. Besides, the costs aren’t high either. It’s important to maintain good relations with the security inspection department. **The intention behind establishing such a department is good, but there are a few bad elements who distort its purpose and functions. There’s nothing you can do about it; you can’t expect everyone to be as excellent as you are. Just ensure good communication.**
7F mentions the key issue!
We ask the Technical Supervision Bureau to conduct inspections every year, mainly to obtain certificates； Verify it by yourself usually
Follow-up question: Does a newly purchased probe need to be tested by the metrology bureau? What are the applicable laws and regulations?
That’s right. Need a third party. rather than the user and the supplier. It’s not a matter of professionalism or not. It’s to prevent you from cheating. Rigorous regulations set by the Safety Supervision Bureau.
