Principle Introduction
The sensing material of TesterMeter-MIX1020 is tin dioxide SnO2, which has low conductivity in clean air. When the Exhaled air 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-MIX1020 Exhaled Air Sensor has high sensitivity to hydrogen sulfide, alcohol, acetone, ammonia etc. It is low cost sensor and adopt TO5 packaging. |
Features
High sensitivity to exhaled air Low power consumption Long life and low cost Fast response and recovery |
Application
Exhaled air detector Health monitor |
