What is the alarm value of the hydrogen chloride gas detector?
Hydrogen chloride is an essential raw material in many industries and has a wide range of uses in industrial production. It is widely used in chemical, petroleum, metal processing, bleaching and dyeing, food, pharmaceutical and other industries, especially in the production of inorganic and organic drugs. However, hydrogen chloride gas has certain hazards to the human body. It will irritate the upper respiratory tract and have a corrosive effect on the eyes, skin, and mucous membranes. In the industrial production process, a hydrogen chloride gas detector is needed. So what is the alarm value of the hydrogen chloride gas detector? The following is Get up and take a look!
Hydrogen chloride gas does not have the characteristics of combustion and explosion, so the alarm value setting of the hydrogen chloride gas detector is mainly based on the occupational exposure limit of hydrogen chloride. According to the relevant information, the occupational exposure limit of hydrogen chloride is 7.5 mg/m³; and based on the toxic gas detector It can be seen from the design standards that the first-level alarm value of the hydrogen chloride gas detector should be less than or equal to 7.5 mg/m³, and the second-level alarm value should be less than or equal to 15 mg/m³.
Hydrogen chloride is widely used in various industries. In the field of organic synthesis, hydrogen chloride reacts with acetylene to produce vinyl chloride and polyvinyl chloride; in the bleaching and dyeing industry, it is used for pickling of cotton after bleaching, neutralizing residual alkali after mercerization, etc.; in steel Pre-plating treatment of parts requires soaking in hydrochloric acid, rust removal before welding, etc.; production of organic drugs, such as vitamin B1, procaine, etc.
It can be seen that hydrogen chloride has many uses. During use, attention should be paid to detecting its concentration changes to avoid personnel poisoning. Here we recommend the fixed hydrogen chloride gas detector ERUN-PG51LX3 produced and sold by Xi'an Yingrun Environmental Protection Company. This instrument It adopts internationally imported sensors with high precision, fast response speed and accurate measurement. It can be customized according to the range and accuracy. It has a large data storage capacity and can save 100,000 pieces of data. It can transmit data through wired or wireless methods. Wired transmission is the most common on the market. The most common 4-20mA signals and RS485 signals meet the different needs of users; explosion-proof and explosion-proof design, IP65 protection, the performance of the instrument is stable, and it is safe and reliable to use.
