Principle Introduction:
As a professional gas sensing solution provider with over 30 years gas sensor manufacture experience, offers Ozone O3 gas sensor.
Sensitive material of MQ-131 gas sensor is semiconductor metallic oxide, which with high conductivity in clean air. When the ozone gas exists, the sensor’s conductivity gets lower along with the gas concentration rising. Users can convert the change of conductivity to correspond output signal of gas concentration through a simple circuit.
MQ-131 ozone gas sensor has high sensitivity to ozone, and also has sensitivity to strong oxide such as Cl2, NO2 &etc. It responses oppositely to organic interference gases.
Features
It has good sensitivity to ozone in wide range, and has advantages such as long lifespan, low cost and simple drive circuit &etc.
