Amphenol SGX Sensortech Solid Polymer Electrochemical Gas Sensors are designed to detect a wide range of gases, including Carbon Monoxide, Chlorine, and Volatile Organic Compounds (VOC), as well as humidity and particulates. The Solid Polymer Gas Sensors are based on the principle of electrochemical catalytic reaction. The sensor responds to the target gas and delivers a very small current proportional to the gas concentration. The SGX Solid Polymer Sensors have a dry core design of three electrodes in contact with the solid electrochemical. A typical electrode consists of a surface area of precious metal and other materials. The electrode, electrochemical, and surrounding air are in contact while the gas diffuses through the back of the porous membrane into the sensor’s working electrode. At this working electrode, the gas is oxidized or reduced.
The Amphenol SGX Sensortech Solid Polymer Electrochemical Gas Sensors are available in a very small size, are highly sensitive, do not use power, and have very low cross-sensitivity to other gases. These qualities make these devices ideal for a wide range of applications, such as offices, classrooms, industrial, and residential properties.
