In this product, the electrochemical three electrodes are arranged in the electrode microchannel of the chip, the working electrode is connected with the reaction microchannel, and the toxic and harmful gases undergo electrochemical oxidation / reduction reaction on the surface of the reaction channel. The type and concentration information of the analyzed gases were obtained by analyzing the changes of electrochemical signals. It can be used for the detection of CO, H2S, SO2, NO, H2, NH3, Cl2, HCN, O3, etc.
