Coming SOON!!!!

Since the release of the original SEC Millenium 22 years ago, our engineers have designed and implemented enhanced optical absorption integrity, lower power consumption and developed software algorithms for our other infrared family of gas detectors and analyzers.  All of this knowledge, experience and features have been incorporated into the SEC Millenium Hawk.

The SEC 5000 IREvolution Infrared gas detector is a rugged reliable microprocessor based intelligent gas detector. The SEC 5000 can be used to monitor for explosive Hydrocarbons, Alcohols, PFCs, Ammonia and many others.
The SEC 5000 IREvolution is ideally suited for use in harsh environments and where the costs of required maintenance for conventional catalytic or electrochemical detectors are prohibitive.  The SEC 5000 IREvolution Infrared gas detector will perform reliably in the presence of silicone and other catalytic poisoning agents and can also operate in oxygen free environments or where high background gas levels are present.  There are no known poisons that affect this technology.
The SEC 5000 IREvolution is a stand-alone device providing a linear continuous 4 to 20 mA output representing 0 to Full Scale.  The SEC 5000 IREvolution can operate as a stand-alone or can be coupled with the SEC 3100 Universal Transmitter, 3120 Dual Transmitter, 3100 DIN Controller or 3120 DIN Controller.
The SEC 5000 also provides a one-wire interactive digital interface and an optional HART Interface.


  • Requires no routine calibration to ensure proper operation.
  • Continuous self-test automatically indicates a fault, with fail to safe operation.
  • A multi-layered filtering system protects optics from dirt and water ingress.
  • Straight optical path eliminates the need for reflective surfaces, such as mirrors or beam splitters.
  • Performs well in the presence of high concentrations or constant background levels of hydrocarbons and in oxygen depleted atmospheres.
  • Highly resistant to poisoning and etching.
  • Standard 4 to 20 mA output (current source)
  • Explosion proof housing designed for harsh environments.
  • Smart Calibration AutoACTM circuit.
