What certifications do gas detectors generally need?
Gas detector is an instrument to detect the concentration of a certain gas in the environment, which 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 purchasing gas detection equipment, we must choose qualified products that meet national standards. So how do we judge whether the equipment is qualified or not and how to avoid buying inferior products?
Generally speaking, a qualified gas detection equipment needs to be certified by the state. Next, Xiaobian will introduce you to what certifications are needed for gas detectors.
1.3C certification
The full name of 3C certification is "Compulsory Product Certification System", with English name China Compulsory Certification and English abbreviation CCC. It is a product conformity assessment system implemented by China government in accordance with laws and regulations to protect consumers' personal safety and national security, strengthen product quality management.
3C logo is usually stuck on the product surface or pressed on the product by molding. If you look closely, you will find a number of oval "CCC" symbols. 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 issuing management center has entered the product corresponding to the code into the computer database, and consumers can inquire about the code through the National Quality Certification Center.
It should be noted that the 3C mark is not a quality mark, but only the most basic safety certification. In other words, this is a national mandatory certification, without which it is not allowed to go on sale.
Second, the explosion-proof certification
Explosion-proof certification is used to determine whether the gas detector meets the requirements of explosion-proof standards, type test and adaptive routine test. If it meets the requirements, the corresponding explosion-proof certification certificate will be issued. When applying for an explosion-proof certificate, the gas detector needs to provide a lot of important information, such as enterprise information certificate, enterprise quality guarantee, technical data, samples submitted for application for explosion-proof certificate, etc., so we should pay attention to check whether there is an explosion-proof certificate when choosing a gas detector.
Three, manufacturing measuring instruments 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 should ask the manufacturer whether they have these two certifications, which determine whether the brand manufacturer can manufacture or repair and install related gas detector equipment.
IV. Inspection Report
Finally, the inspection report on the gas detector, which is preferably issued by the authoritative measuring instrument department of the country, contains various parameters, functions and detailed data of this gas detector, which can help us to understand this instrument as soon as possible.
When we buy gas detectors, we should focus on checking whether the products have these four aspects of certification, so as to avoid buying fake and shoddy products and bringing unnecessary trouble to the production of enterprises.
