How Electrochemical Gas Sensors and Detectors Work

An electrochemical gas sensor is available for just about any target gas, and across a wide range of sensitivities, such as a highly accurate electrochemical CO sensor. Although they are designed to be as specific as possible, most electrochemical sensors will respond in some manner to gases other than the target gas. This is called cross-sensitivity and is a result of the sensor’s ...
