YJJ The company sells 7CO-1000 CO electrochemical sensors

Carbon monoxide gas sensor 7CO-1000

Carbon monoxide CO electrochemical sensor consists of three electrodes, platinum wire and liquid electrolyte.The three electrodes are working electrode (S), opposite electrode (C) and reference electrode (R).The carbon monoxide gas passes through the hole on the top of the shell and the filter plate to reduce the interference of sulfur dioxide and hydrogen sulfide.Carbon monoxide reacts with the electrolyte to produce an electric current, which is proportional to the concentration of carbon monoxide (PPM).
