How Electrochemical Gas Sensors and Detectors Work

electrochemical gas sensor measures the concentration of a target gas by using oxidation or reduction reactions to generate positive or negative current flow through an external circuit. The basic components of an electrochemical sensor include a “working” electrode, a “counter” electrode and in most case a “reference” electrode.

Signal conditioning for electrochemical sensors

Electrochemical sensors are widely used in the medical sector. For example, to monitor the concentration of glucose in the blood of diabetic patients, a glucometer (glucose meter) is used. In this case, the disposable test strips are the electrochemical sensors. Figure 1 illustrates the carbon monoxide and the glucometer test-strip sensors ...

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 ...
