OFS-2000 Series Optical Flow Sensor
In 1999 we took the optical tracking techniques developed from the LOA Long-baseline Optical Anemometer, and applied them on a smaller scale. Result: the most accurate air flow sensor ever - the OFS 2000.

Originally designed for industry to assist measurement of greenhouse gas emissions, further refinements have proven their use in process control, flare stack monitoring, tunnel vents, combustion control - and more. OFS-2000 series sensors meet EPA 40 Parts 60 & 75 and are in service in power plants, mines, refineries, incinerators - wherever they can serve - throughout the world

LOA-105 Optical Anemometer - Industrial LOA-105
Before OFS, there was LOA - with a 3Km range developed for industrial use to handle large interior areas. Used world-wide to monitor aluminum smelting pot rooms. It's superior accuracy and resistance to harsh environments make it the sensor of choice.
