Product Details:
MG-812 is a semiconductor oxide chemical sensor that uses the principle of solid electrolyte batteries to detect CO2. When the sensor is kept at a certain operating temperature and placed in a CO2 atmosphere, the positive and negative electrodes of the battery react with each other, and an electromotive force is generated between the sensor's sensitive electrode and the reference electrode. The change of test signal voltage can detect the change of CO2 concentration.
Features:
MG-812 gas sensor has a smaller volume, lower power consumption, higher sensitivity and good selectivity to CO2, less affected by changes in temperature and humidity, and the sensor signal has good stability and repeatability .
Application:
It is applied to the detection of CO2 concentration in air quality control systems, fermentation process control systems and greenhouses.
