Principle Introduction
| The sensing material of TesterMeter-MIX1016 is tin dioxide SnO2, which has low conductivity in clean air. When the Hydrogen Sulfide 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 -MIX1016 Hydrogen Sulfide(H2S) Gas Sensor has high sensitivity to Hydrogen Sulfide. The sensor can work in high temperature. It is low cost sensor and can be used in different applications. |
