Production Description:
ME3-H2 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.
Feature:

  • Low consumption
  • High precision
  • High sensitivity
  • Wide linear range
  • Good anti-interference ability
  • Excellent repeatability and stability
