Electrochemical Integrated Gas Sensor ME2-CS03

  • ME2-CS03.png


The gas sensor adopts a high-sensitivity chemical formula. It can detect the toxic and harmful gas generated by the thermal runaway combustion caused by the internal short circuit, overcharge, overdischarge and collision of the power battery, and the redox reaction between the combustible gas and oxygen to form a current signal. The perception, intelligent judgment and early warning of early battery fire can protect the personal safety of electric vehicles and passenger drivers to the greatest extent, and open up a life channel for the evacuation of drivers and customers.


High sensitivity, can detect trace gas components emitted by the battery in the early stage of thermal runaway, and realize early detection of fire;

Zero power consumption, using current-type signal output, the sensor itself has no power consumption, and can detect when the battery is dormant;

Strong anti-interference ability, strong selectivity to the measured gas, and will not be disturbed by dust; Excellent repeatability and stability, and the test error range of the same concentration is small.
