Detcon Model IR-540 Detectors are non-intrusive "smart" sensors designed to detect and monitor carbon dioxide.
The available detection ranges are 0-0.3%, 0-1%, 0-3% and 0-5% 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.
CSA and UL Listed: Class I, Division 1, Groups B, C and D
Simple Menu Driven Calibration - takes less than 3 minutes
Backlit LCD and LED indicators for FAULT and CAL status
Field replaceable miniature optical sensor
Pluggable field replaceable transmitter
Low energy consumption
Expected life of the 5 year sensor
