Fixed NO gas detector CRH-80D with 4-20mA output.

    Fixed gas detector, NO gas detector, fixed gas monitor, gas detector supplier.

    Model CRH-80D is fixed gas detector for nitrogen oxide (NO) gas detection. It is a new type gas detector which used imported high quality gas sensor and advanced, microcontroller technology. Original imported electrochemical sensor is with good repeatability, long working life and fast response.


    1)  Common measurement range is 0-10ppm. Resolution is 0.1ppm.

    2)  LED display clearly shows NO gas leak concentration data.

    3)  Standard signal of 4-20mA current signal or RS485 digital signal output, can directly connect to PLC or other controller.

    4)  Remotely operated by a infrared remote controller.


    1) High

    sensibility, rapid response, good linearity and short polarization period;

    2) Two passive contact relay output;

    3) Explosion-proof design complies with the requirement of applying in Zone 1,2.

    4) Cast aluminum body, soid and durable.

    In order to inspect the gas detector, we can provide matched gas control unit model CRGD-M1 and CRGD-M2. It will display the concentration from each connected gas detector. They can receive 4-20mA signal and RS485 signal at the same timr. One control unit  can inspect more than 70 pc gas detector at most.


    4-20mA standard output signal, wall-mounted gas detector for NO gas, relay output, explosion-proof enclosure.
