    Detailed introduction

    JH-TCQ-XX (BFL)

    Product introduction:
    The imported electrochemical sensor is used. It applies the principle of controlled potential electrolysis. Its structure is to place three electrodes in the electrolytic cell, namely the working electrode, the counter electrode and the reference electrode, and apply a certain polarization voltage to replace different gases. The sensor can change the value of the polarization voltage to measure different toxic and harmful gases. The measured gas reaches the working electrode through the membrane, and a redox reaction occurs. The sensor will output a small current at this time. This current is proportional to the concentration of the toxic and harmful gas. This current signal is converted into a voltage by sampling and the voltage signal is amplified. After voltage and current conversion, the content (ppm value) in the detection range of toxic and harmful gases is converted into 4-20mA standard signal output.


    Features:
    ☞ The imported electrochemical sensor has the characteristics of strong gas selectivity, short response time, long service life, high accuracy, and strong anti-interference.
    ☞ It can detect various toxic gases in the indoor and outdoor environment and transmit the detection signal to the gas alarm controller ;
    ☞The shell is made of cast aluminum alloy, the surface is painted, explosion-proof, dust-proof and corrosion-resistant, which can meet the requirements of various environments.
    ☞ This detector can be connected to any secondary instrument or control system capable of receiving 4-20mA standard signals;


    Detection gas:

    Hydrogen, oxygen, acetone, ethylene oxide, ammonia, chlorine, hydrogen sulfide, carbon monoxide, nitrogen monoxide, nitrogen dioxide, sulfur dioxide
    Phosgene, hydrogen chloride, phosphine, arsenide, chlorine dioxide, hydrogen cyanide,
    Various toxic and harmful gases such as toluene, acetylene, chloroform (trichloromethane)


    Application areas:
    Petroleum, chemical, metallurgy, coking, pharmaceutical, sewage treatment, boiler room, hotel and other special industries and environmental fields.
