  • Principle Introduction
Principle Introduction:
Chemical Sensor MG-811 adopts solid electrolyte battery principle to detect carbon dioxide. When the sensor is placed in the CO2 environment, the electrode reaction occurs between the battery positive and negative electrode, and electromotive force is generated between the sensor sensitive electrode and reference electrode. The output voltage signal can be used for carbon dioxide detection.
