The OXYvisor is a process oxygen analyzer, best utilized to measure oxygen concentration in continuous, online, process monitoring and control applications. The device utilizes an optical quench luminescent technique to measure oxygen concentration by volume (ppmv, molar basis) in gas phase or dissolved oxygen measurement (ppbv, ppmv) in liquid and aqueous phase applications. The oxygen meter is coupled, via a flexible fiber optic cable, of optional lengths, to a small external oxygen sensor that can be placed into an extracted sample stream, or directly in-situ to the process stream as a gaseous oxygen sensor or when used in liquids as a dissolved oxygen probe dissolved probe or optical DO sensor.
