Product Description:
ME4-HF Electrochemical Hydrogen Fluoride Sensor Is Used For Hydrogen Fluoride Detection In Industrial And Environmental Fields
Features:
ME4 - HF HF type sensor is the constant potential electrolysis sensor, hydrogen fluoride gas inside the sensor in a series of REDOX reaction and release charge current formation, the size of the current is proportional to the concentration of hydrogen fluoride and follow the Faraday's law, through the test current to determine the size of the hydrogen fluoride concentration.
