Detcon Model IR-642 Detectors are non-intrusive "smart" sensors designed to detect and monitor carbon dioxide.
The available detection ranges 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 splash guard with integral cal port, a pluggable control emitter circuit, a basic connection board and an explosion-proof enclosure.
