Principle Introduction
| MEWOI-MIX8060 Hydrogen (H2) Gas Sensor is a battery operable electrochemical sensor developed by Mixsen. Hygrogen and oxygen on the working electrode and counter electrode are subjected to oxidation-reduction reaction correspondingly. This produces the electric current. The current is directly proportional to the concentration of hydrogen and following the Faraday’s law. Through measure the current to get the concentration of hydrogen. |
Features
High selectivity and sensitivity to H2 High accuracy Linear output Long life Environmental protection design |
Application
Vehicle new energy hydrogen leakage monitoring H2 leakage monitoring for industrial |
