Hydrogen Sensor
FS02500 is a fuel cell type electrochemical sensor, the reduction reaction occurs on the working electrode and the opposite electrode, and the charge is released to form a current, the current generated is proportional to the concentration of hydrogen and follows Faraday's law, and the hydrogen concentration can be determined by testing the size of the current.
