Joint testing of SIN-ADI5000 industrial composite nitrate nitrogen electrode

Based on the principle of electrochemical reaction for measurement. The nitrate nitrogen electrode mainly consists of two electrodes: the working electrode and the reference electrode. The working electrode is a metal electrode, usually a silver electrode. When nitrate ions and silver ions meet at the working electrode, they undergo a redox reaction, which is reversible. That is to say, nitrate ions can oxidize silver ions, while silver ions can be reduced to nitrate ions; The reference electrode is the same electrode that does not participate in the reaction, usually a silver/silver oxide electrode. Its function is to provide a stable reference unit for measuring changes in the working electrode potential.
