IR-640 Carbon Dioxide Sensor
Manufacturer: Teledyne| DetconDetcon Model IR-640 sensors are non-intrusive “Smart” sensors designed to detect and monitor Carbon Dioxide.
Available ranges of detection 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 splashguard with integral cal port, a plug-in control transmitter circuit, a base connector board and an explosion proof enclosure.
