ME3-

HF Electrochemical Hydrogen Fluoride Sensor

ME3-HF electrochemical sensor detect gas concentration by measuring current based on the
electrochemical principle, which utilizes the electrochemical oxidation process of target gas on the
working electrode inside the electrolytic cell, the current produced in electrochemical reaction of the
target gas are in direct proportion with its concentration while following Faraday law, then concentration
of the gas could be get by measuring value of current.
