Principle Introduction
The sensing material of TesterMeter-MIX1037 Ammonia(NH3) Gas Sensor is tin dioxide SnO2, which has low conductivity in clean air. When the ammonia 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-MIX1037 ammonia (NH3) gas sensor has high sensitivity to ammonia gas. Ammonia (NH3) 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 NH3 gas * High sensitivity to NH3 * Long life and low cost * High ant seismic |
Application
* Domestic gas leakage detectors * Portable gas detectors |
