Production Description:
MG-812 is a semiconductor oxide chemical sensor that uses solid electrolyte battery principles to detect CO2.
When the sensor is kept at a certain working temperature and placed in a CO2 atmosphere, an electrode reaction occurs between the positive and negative electrodes of the battery, and the output signal voltage is inversely proportional to the logarithm of the CO2 concentration. A voltage change in the test signal can detect a change in the CO2 concentration.
Feature:

  • Small sizes, low power-consumption, high sensitivity and good selectivity.
  • Less affection by temperature and humidity.
  • Good stability and repeatability.

Application:
CO2 detection in air quality control, ferment process control and green house fields.
