SEC Millenium Infrared Hydrocarbon Gas
Detector
The SEC Millenium is an optical gas Detector utilizing Infrared technology to measure ambient hydrocarbon gas concentrations in harsh environments. The Millenium employs patented optical compensation techniques to ensure reliable trouble-free operation in the most difficult applications while requiring little maintenance. The industry standard 4-20 mA output provides gas concentration as well as unit status information. The Millenium is an excellent upgrade for catalytic bead sensors.
