Electrochemical Sensors (4 Series)
SGX electrochemical sensors are a type of fuel cell. These sensors detect gases by producing a chemical reaction between the gas and oxygen contained in the sensor. The reaction produces a small current, which is proportional to the concentration of the gas present.
