Principle Introduction:
Sensitive material of MIX1037 NH3 gas sensor is SnO2, which with lower conductivity in clean air. When NH3 gas exists, the sensor’s conductivity gets higher along with the gas concentration rising. Users can convert the change of conductivity to correspond output signal of gas concentration through a simple circuit.
MIX1037 ammonia gas sensor has high sensitivity to NH3 gas, also can monitor organic amine such as trimethylamine, cholamine well. It can detect kinds of gases including ammonia and is a kind of low-cost sensor for kinds of applications
Feature:
* High sensitivity to wide range of NH3 gas
* Long life and low cost
* High ant seismic
Application:
* Domestic gas leakage detectors
* Portable gas detectors
* Domestic NH3 gas alarm
* Industrial NH3 gas leakage alarm
