Which licenses are typically need for gas detectors?
The 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 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 certified by the state. Next, the editor will introduce to you which 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 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 compulsory 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 national mandatory certification, and 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 the explosion-proof standard, type test and adaptation. If it meets the requirements, the 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 inspection samples for applying for an explosion-proof certificate. Therefore, we should pay attention to checking whether there is explosion-proof when choosing a gas detector. certificate.
3. Manufacturing measuring instrument license and explosion-proof electrical equipment installation and repair qualification certificate
These two certifications are not for the gas detector itself, but for the manufacturer of the gas detector. When purchasing, we need to ask whether the manufacturer has these two certifications. These two certifications determine Whether the brand manufacturer can manufacture or repair and install related gas detector equipment.
4. Inspection report
Finally, the inspection report on the gas detector. This 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 this gas detector, which can help us as soon as possible. Get to know this instrument.
When we purchase gas detectors, we should focus on checking whether the products have these four certifications, so as to avoid buying fake and shoddy products and bring unnecessary troubles to the production of enterprises.
