Gas detector is an instrument for detecting the concentration of a certain gas in the environment. It is widely used in chemical industry, metallurgy, underground pipe gallery, power electronics, medicine and other industries to protect the safe production of enterprises. Therefore, when we buy gas detection equipment, we must choose qualified products that meet national standards. So when we buy a gas detector, we need to know what certification manufacturers.

1. explosion-proof certification:

& nbsp;

Explosion-proof certification is a routine test used to determine whether the gas detector meets the requirements of explosion-proof standards, type tests and adaptation. If it meets the requirements, the corresponding explosion-proof certification certificate will be issued. When applying for explosion-proof certificate, gas detector needs to provide many important materials such as enterprise qualification, enterprise quality guarantee, technical data, samples for explosion-proof certificate, etc.

2 inspection report and 3C certification:

& nbsp;

the inspection report of the gas detector should be the inspection report issued by the national authoritative measuring instrument department. The content of the test report includes various parameters, functions and detailed data of the gas detector, which helps us to understand the gas detector as soon as possible.

3C certification is called "mandatory product certification system". It is a product conformity assessment system implemented by the Chinese government in accordance with laws and regulations to protect consumers' personal safety and national security, strengthen product quality management. It should be noted that the 3C mark is not a quality mark, but 1 a basic safety certification. In other words, this is a national compulsory certification. Without this certification, it is not allowed to be sold on the market.
