What certifications are generally required for gas detectors?
Gas detectors are instruments that detect the concentration of certain gases in the environment. They are widely used in chemical industry, metallurgy, underground pipe corridors, power electronics, medicine and other industries to protect the safe production of enterprises. Therefore, when we purchase gas detection equipment, we must choose qualified products that meet national standards. So how do we judge whether the equipment is qualified and how to avoid buying inferior products?
Generally speaking, a qualified gas detection equipment needs to be nationally certified. Next, the editor will introduce to you what certifications are required for gas detectors.
1.3C certification
The full name of 3C certification is "Compulsory Product Certification System", the English name is China Compulsory Certification, and the English abbreviation is CCC. 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.
The 3C mark is usually affixed to the surface of the product or pressed on the product through molding. If you look carefully, you will find multiple oval "CCC" marks. There is a random code behind each 3C logo, and each random code has a corresponding manufacturer and product. When the certification mark issuance and management center issues the compulsory product certification mark, the product corresponding to the code has been entered into the computer database, and consumers can query the code through the National Quality Certification Center.
It should be noted that the 3C mark is not a quality mark, but only a basic safety certification. In other words, this is a mandatory national certification. Without this certification, it is not allowed to be put on the market.
Explosion-proof certification
Explosion-proof certification is a routine test used to determine whether a gas detector meets the requirements of explosion-proof standards, type testing and adaptation. If it meets the requirements, a corresponding explosion-proof certification will be issued. When applying for an explosion-proof certificate, a gas detector needs to provide many important information such as enterprise qualifications, enterprise quality assurance certificate, technical information, and samples for inspection when applying for an explosion-proof certificate. Therefore, when choosing a gas detector, we should pay attention to check whether it is explosion-proof. Certificate of conformity.
License for manufacturing measuring instruments and qualification certificate for installation and repair of explosion-proof electrical equipment
These two certifications are not for the gas detector itself, but for the manufacturer of the gas detector. When purchasing, we need to ask the manufacturer whether it has these two certifications. These two certifications determine Whether this brand manufacturer can produce, manufacture, repair and install related gas detector equipment.
Inspection Report
Finally, there is the inspection report about the gas detector. This inspection report should preferably be an inspection report issued by the country's authoritative measuring instrument department. It contains various parameters, functions and detailed data of the gas detector, which can help us as quickly as possible. Get to know this instrument.
