R200 Freon Gas Sensor Semiconductor Gas Detection Sensor 10～1000ppm Refrigerant Sensor
MIX2021 10～1000ppm Freon Gas Leakage Detection Sensor
Principle Introduction:
The sensing material of MIX2021 Freon Gas Sensor is tin dioxide SnO2, which has low conductivity in clean air. When the Freon 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.
Feature:
High sensitivity
Low power consumption
Long life and low cost
Fast response and recovery
Application:
Environmental leakage of Freon
