Ammonia Gas Sensor

AMMONIA SENSOR

RY-CNH3

MANUAL

INTRODUCTION

The NH3 sensor according to the principle of electrochemistry, uses the electrochemical oxidation process of the gas to be measured on the working electrode in the electrolytic cell. The working electrode and the reference electrode of the electrolytic cell are kept at a proper potential by the electronic circuit. The electrochemical oxidation of the gas under test can occur, because the Faraday current generated by the oxygen during the oxidation and reduction reactions is small and can be ignored, so the current generated by the electrochemical reaction of the gas under test is proportional to its concentration and follows Faraday's law . In this way, the concentration of the gas to be measured can be determined by measuring the magnitude of the current.
