product details
ME2-H2A hydrogen sensor is a fuel cell type sensor, in which hydrogen and oxygen undergo corresponding oxidation-reduction reactions on the working electrode and counter electrode, releasing charges to form a current. The magnitude of the generated current is proportional to the concentration of hydrogen and follows Faraday's law. By measuring the magnitude of the current, the concentration of hydrogen can be determined.
Sensor characteristics
Low power consumption, high precision, high sensitivity, wide linear range, strong anti-interference ability, excellent repeatability and stability.
Main applications
Widely suitable for hydrogen concentration detection in commercial, especially civilian fields.
