Principle Introduction
| The sensing material of MEWOI-MIX1061 Ozone(O3) Gas Sensor is tin dioxide SnO2, which has low conductivity in clean air. When the ozone gas exists, the conductivity of the sensor will be raise according to the gas concentration goes up. Through a simple circuit, to convert the changes of conductivity to correspond to the gas concentration. |
Features
High sensitivity to wide range of ozone High sensitivity to ozone Long life and low cost High anti-seismic |
Application
Domestic O3 gas leakage detectors Portable Ozone gas detectors |
