Hydrogen fluoride is a colorless toxic corrosive gas with pungent odor and strong irritation. It doesn't burn. At room temperature and pressure, it is a colorless smoky liquid that flows easily. Easily soluble in water, usually become 50% to 60% aqueous solution, that is, fluorohydroacid. It has a polymerization action, so it exists in an aqueous solution as H2F2 or H3F3. Hydrogen fluoride dissolves in contact with moisture in the air and becomes smoky.
The corrosive effect of hydrogen fluoride is very strong, and many materials are corroded by it. It can interact with most metals to form fluoride and hydrogen. React with oxides and hydroxides of alkaline earth metals, alkali metals, silver, lead, zinc, mercury and iron to form water and fluoride. Reacts violently with halides to form fluoride and hydrogen halides. In the presence of oxygen, it also reacts easily with copper. Strong affinity for water. It can act as dehydrating agent of organic compounds, reagent of fluorination reaction, promoter of polymerization reaction and catalyst of water decomposition reaction. It has the characteristics of corrosion to silicate such as glass.

The instrument is compatible with various alarm controllers, PLC, DCS and other control systems, which can realize remote monitoring, remote alarm, computer data storage and other functions.
The detector is used in the field of multi-functional hydrogen fluoride detector concentration 24 hours continuous online monitoring and temperature and humidity measurement, can simultaneously detect 1 ~ 4 kinds of gas concentration and temperature and humidity, on-site display concentration and exceeded sound and light alarm, remote data transmission.
The stationary hydrogen fluoride (HF) gas detector is used to continuously monitor the concentration of hydrogen fluoride gas in the environment, and is widely used in chemical industry, semiconductor manufacturing, metallurgy and other industries to ensure the safety of the working environment. The detector mainly detects hydrogen fluoride concentration by electrochemical sensor or infrared sensor. A current is generated by the reaction of the gas with the electrolyte in the sensor, and the current is proportional to the concentration of the gas.
Fixed hydrogen fluoride HF gas detector is mainly used to monitor the concentration of hydrogen fluoride gas in the environment to ensure industrial safety and environmental protection. The following are the main areas of application: monitoring the production, storage and use of hydrogen fluoride to prevent leaks; Used to monitor the release of hydrogen fluoride during the synthesis of organic fluorine compounds; In the process of electrolytic aluminum, the release of hydrogen fluoride is monitored to reduce environmental pollution.
