MG-812 MG812 Is A Semiconductor Oxide Chemical Sensor That Uses The Principle Of A Solid Electrolyte Battery To Detect CO2
Product description:
MG-812 is a semiconductor oxide chemical sensor that uses the principle of a solid electrolyte battery to detect CO2. When the sensor is kept at a certain operating temperature and placed in a CO2 atmosphere, electrode reaction occurs in the positive and negative electrodes of the battery, electromotive force is generated between the sensor sensitive electrode and the reference electrode, and the output signal voltage is inversely proportional to the logarithm of the CO2 concentration
For example, by measuring the change of signal voltage, the change of CO2 concentration can be detected.
Sensor characteristics:
MG-812 gas sensor has small volume, low power consumption, high sensitivity and good selectivity to CO2, and is less affected by temperature and humidity changes, and the sensor signal has good stability and repeatability.
Main application:
Used in air quality control system, fermentation process control system and greenhouse and other places CO2 concentration detection.
