Principle Introduction:
MIX8417 Hydrogen(H2 ) gas sensor is an electrochemical sensor developed by Mixsen. It uses the principle of electrochemistry. There is a reference electrode inside the sensor, which greatly improves the stability of the sensors. When the sensor senses the hydrogen, the working electrode and the counter electrode react with the redox reaction, through measure the current to get the concentration of hydrogen.
Feature:
High selectivity & sensitivity to H2
High accuracy
Linear output
Application:
Industrial monitors leakage detection
Transformer hydrogen detection
