BrandWinsen
Sensing PrincipleElectrochemical
Target GasH2
Product TypeElectrochemical Hydrogen Sensor
Hydrogen Sensing for OEM Integration
Product Overview
A long-life fuel-cell H2 sensor for commercial, automotive and small-generator hydrogen concentration monitoring.
MEv-GH01 detects hydrogen by measuring the current generated by electrochemical oxidation of the target gas at the working electrode.
The output current is proportional to hydrogen concentration according to Faraday’s law, supporting accurate concentration measurement with external signal conditioning.
