A gas detector is a device that measures the amount of a certain gas present in the surrounding air. To ensure that businesses are producing safely, it is widely employed in the chemical industry, metallurgy, underground pipe gallery, power electronics, medicine, and other sectors of the economy. Therefore, we must pick reputable products that adhere to national criteria when we buy gas detection equipment. How then can we determine whether the equipment is suitable or not, and how do we steer clear of purchasing subpar goods?
Generally speaking, a qualified gas detection equipment needs to be certified by the state. Next, I 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 in order to protect the personal safety and national security of consumers and strengthen product quality management.
The 3C logo is generally pasted on the surface of the product, or pressed on the product by molding. If you look closely, 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 issuing the mandatory product certification mark, the certification mark issuance management center has entered the product corresponding to the code 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. That is to say, this is a compulsory certification of the state, without this certification, it is not allowed to be sold on the market.
2. Explosion-proof certification
Explosion-proof certification is a routine test used to determine whether the 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 a lot of important information such as enterprise qualification certificate, enterprise quality assurance certificate, technical information, and samples for inspection of the explosion-proof certificate. Therefore, we should pay attention to check whether there is explosion-proof when choosing a gas detector. Certificate of Qualification.
3. 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 certification of the manufacturer of the gas detector. When purchasing, we need to ask the manufacturer whether they have these two certificates. These two certificates determine the Whether the brand manufacturer can manufacture or repair and install related gas detector equipment.
4. Inspection report
Finally, there is the inspection report about the gas detector. The inspection report should preferably be the inspection report issued by the national authoritative measuring instrument department. It contains various parameters, functions and detailed data of the gas detector, which can help us to quickly Learn about this instrument.
When purchasing a gas detector, we should focus on checking whether the product has these four certifications, so as not to buy fake and shoddy products, which will bring unnecessary trouble to the production of enterprises.
