    JD-D65NA type independent optical smoke fire detector is a newly developed wireless detector with NB.

    The gas-sensitive material used by the JT-JD-D63C domestic combustible gas detector is tin dioxide (SnO2), which has a low conductivity in clean air. When there is combustible gas in the environment of the detector, the conductivity of the detector increases with the increase of the combustible gas concentration in the air. A simple circuit is used to convert the change in conductivity into an output signal corresponding to the concentration of the gas. And the detector has high sensitivity to methane and strong anti-interference ability to alcohol and some other interfering gases.
