- • Detection Gas: Ozone, O3
- • Detection Range: 10～1000ppb Ozone
- • Application: It is widely used in domestic ozone concentration alarm, industrial ozone concentration alarm and portable ozone concentration detector.
- 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 WO3, which with lower 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.
