Principle Introduction:
Winsen Electronics produce oxygen gas sensor, O2 sensor, adopting fuel cell working principle.
ME2-O2-Ф20 electrochemical sensor detects 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 the electrochemical reaction of the target gas is in direct proportion with its concentration while following Faraday law, then the concentration of the gas could be got by measuring the value of current.
Applications :
Detecting O2 in mine, industry and environmental protection field.
