Introduction to Electrochemical (EC) Gas Sensors

SGX electrochemical sensors detect gases by producing a chemical reaction between the gas and oxygen contained in the sensor. This reaction produces a small current, which is proportional to the concentration of the gas present. The sensor is, in effect, a type of fuel cell. Reactions occur on two electrodes which when combined together produce the sensing process. These electrodes comprise ...

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 ...

Carbon Monoxide (CO) Detection - System Sensor

Electrochemical detectors are the newest, most reliable CO detectors available. They take the most accurate readings of CO, from low levels of CO that may be hazardous over long periods of time to high concentrations that present an immediate danger. They are also less prone to false alarms than other types of CO sensing technologies.
