Introduction of toxic gas detector

The detector consists of a miniature plug-in electrochemical sensor in a 3166 stainless steel housing, an epoxy-encapsulated Intelligent Transmitter Module (ITM), and a sensor splash guard. This plug-in smart sensor can automatically recognize ITM and can achieve seamless connection in the field. The operator operates with a magnetic rod. One of the main features is that its software can guide the user to operate according to the program and the menu displayed by the LED.

In the production process, the toxic and harmful gases discharged into the air of the workplace not only directly affect the safety and health of the operator, but also pollute the surrounding environment. Especially the production process with outdated equipment and backward technology,

The detectable gases are C2H3O; acetylene C2H2; acrylonitrile C3H3N; ammonia NH3; AsH3; bromine gas Br2; butadiene C4H6; carbon disulfide CS2; carbon monoxide CO; carbon oxysulfide COS; chlorine Cl2; chlorine dioxide ClO2; ethene Borane B2H6; dimethyl sulfide C2H6S; ethanol C2H5OH; ethyl mercaptan C2H5SH; ethylene C2H4; ethylene oxide C2H4O; fluorine gas F2; formaldehyde CH2O; germane GeH4; hydrazine N2H4; hydrogen H2 (ppm); bromide Hydrogen HBr; Hydrogen chloride HCl; Hydrogen cyanate HCN; Hydrogen fluoride HF; Hydrogen sulfide H2S; Methanol CH3OH; Methanethiol CH3SH; Nitric oxide NO; Nitrogen dioxide NO2; Ozone O3; Phosgene COCl2; Phosphine PH3; Silane SiH4 ; Sulfur dioxide SO2; tetrahydrothiophene C4H8S; thiophene C4hH4S; toluene C6H5CH3; vinyl acetate C4H6O2; vinyl chloride C2H3Cl and more than 60 conventional toxic gases.

The toxic gas detector is widely used in various petroleum, petrochemical and chemical production equipment areas; municipal, fire protection, gas, telecommunications, coal, metallurgy, electric power, medicine, food processing and other places with toxic and harmful gases.

Classification and principle of toxic and harmful gas detectors: The key component of a gas detector is a gas sensor.
Gas sensors can be divided into three categories in principle:
A) Gas sensors using physical and chemical properties: such as semiconductor type (surface control type, volume control type, surface potential type), catalytic combustion type, solid thermal conductivity type, etc.
B) Gas sensors using physical properties: such as thermal conductivity, light interference, and infrared absorption.
C) Gas sensors using electrochemical properties: such as constant potential electrolytic type, Galvanic battery type, diaphragm ion electrode type, fixed electrolyte type, etc.
