Description

Winsen MG812 Solid Electrolyte Carbon Dioxide (CO₂) Gas Sensor

The MG812 CO₂ Gas Sensor is a chemical-type gas sensor based on the solid electrolyte cell principle, designed for accurate detection of carbon dioxide (CO₂). When exposed to CO₂, electrochemical reactions occur between the positive and negative electrodes, generating an electromotive force (EMF) between the sensitive electrode and the reference electrode. This EMF output voltage is proportional to the CO₂ concentration.

The MG812 sensor offers high sensitivity, good selectivity, and stable repeatability, with minimal influence from temperature and humidity. Its compact size and low power consumption make it suitable for long-term CO₂ monitoring in industrial and environmental applications.
