Grove - Oxygen Sensor(ME2-O2-Ф20) can be used to make a simple oxygen level detector and analyser. It can measure O2 concentration within a range of 0 to 25% Vol and the max detecting concentration is 30% Vol. ME2-O2-Ф20 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. Typical application includes oxygen analyser, air purifier and environmental monitoring. It is also suitable for detecting O2 in mine, industry and environmental protection field.
