Overview
NL3-G4-27E26 electrochemical gas sensor is fuel cell type, which utilizes the electrochemical oxidation process of O3 gas on the working electrode. 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.
Key Features
