Principle Introduction
The sensing material of TesterMeter-MIX1005B LPG&CH4 Gas Sensoris tin dioxide SnO2, which has low conductivity in clean air. When the combustible 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. TesterMeter-MIX1005B Combustible Gas Sensor has high sensitivity to LPG /CH4 and methane the sensor can work in high temperature. It is low cost sensor and can be used in different applications. |
Features
* High sensitivity to wide range of LPG and CH4 * Long life * Low cost * High ant seismic |
Application
* Domestic gas leakage detectors * Portable gas detectors |
