HCL gas chemical characteristics
Hydrogen chloride (HCl) is a colorless gas with a pungent, irritating odor. It is a strong acid that can corrode many metals and organic matter. HCl can react with many substances at high temperatures, including hydrogen, oxygen, sulfur, nitrogen, chlorine, and fluorine. In water, HCl forms hydrochloric acid, which is a common laboratory reagent and industrial chemical. HCl is a toxic gas, and high concentrations of HCl gas can cause severe irritation and damage to the human body, and can even cause death. HCl hydrogen chloride gas is produced in chemical processes and industrial manufacturing production projects. In addition, HCl gas may also be produced in industries such as mining, chemicals, pharmaceuticals, pulp and paper, leather processing, and pesticide production. In addition, HCl may also be produced in accidents or fires.
HCl gas TLV and poisoning reaction
Workshop air hygiene standards: China MAC 15mg/m3; American ACGIH Hydrogen chloride TLV-C 7.5mg/m3, high concentrations of HCl gas can cause irritation and damage to the human body. Poisoning symptoms include eye and respiratory irritation, cough, sore throat, pulmonary edema and bronchospasm. High concentrations of HCl gas can cause serious irritation and damage to the human body, and even cause death.

HCl gas sensors are widely used in the following fields or industries:
Chemical industry
HCl gas is a common industrial waste gas in the chemical production process and needs to be detected and monitored.
Environmental protection
HCl gas is a harmful gas and has strict restrictions on the concentration allowed to be discharged into the atmosphere from industrial production.
Mining industry
HCl gas is produced during metal smelting and ore extraction.
Textile industry
Monitoring the dyeing and finishing process of textiles.
Solar cell industry
The production process of monocrystalline silicon and production waste gas emissions need to be strictly monitored and controlled. HCl gas sensors can detect and monitor the concentration of HCl gas in real time, detect and deal with HCl gas leakage or exceeding the standard in a timely manner, and ensure production safety and environmental health.
In addition, Tensensor HCL sensor also has the advantages of low power consumption, high precision, wide linear range, strong anti-interference ability, good repeatability and stability, etc. It can be widely used in the detection of hydrogen chloride in industry, mining and environmental protection fields.
Tensensor's gas sensors have been widely used in various industries and fields, especially in the field of industrial monitoring. They can achieve PPB-level detection resolution, strong anti-interference, stable and reliable, greatly improved measurement accuracy, and high user recognition, especially in the field of industrial safety, portable detectors, fixed industrial detection alarms, oxygen analyzers, online monitoring system integration, etc.
