Principle Introduction
| The sensing material of TesterMeter-MIX1002 is 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. MIX1002 Combustible and Smoke Gas Sensor has high sensitivity to methane, propane butane etc. combustible gas. The sensor can work in high temperature. It is low cost sensor and can be used in different applications. |
