Detcon Model IR-642 sensors are non-intrusive “Smart” sensors designed to detect and monitor Carbon Dioxide. 

Available ranges of detection are 0-10%, 0-25%, 0-50%, and 0-100% by volume. 

The sensor assembly consists of a miniature infrared optical sensor in a stainless steel housing that includes a splashguard with integral cal port, a plug-in control transmitter circuit, a base connector board and an explosion proof enclosure.
