Product Overview
A compact electrochemical H2 sensor for industrial and environmental hydrogen detection.
ME3-H2 measures hydrogen concentration by detecting the electrochemical current generated by oxidation of H2 at the working electrode.
The current is proportional to gas concentration according to Faraday’s law, supporting linear concentration measurement through external circuitry.
Designed for Reliable Integration
