IR Gas Sensors

Amphenol SGX Sensortech IR Gas Sensors use the non-dispersive infrared (NDIR) principle to detect and monitor the presence of carbon dioxide, hydrocarbons, and acetylene gases. These low-power sensors are built with a rugged stainless steel construction and no moving parts, providing reliable, fail-safe operation with low maintenance. Amphenol SGX Sensortech IR Gas Sensors feature an immunity from "poisoning."
