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.
