The product

Utilizing an optical quench luminescence approach, the OxyHound offers precise oxygen measurements in a gaseous phase (ppmv, on a molar basis). It features a user-friendly design, including a flexible fiber optic cable connected to a compact sensor that is easily serviceable in the eld. The OxyHound is designed to cater to a wide range of industrial environments. Its robust construction and extensive safety designs make it a reliable choice for indoor and outdoor settings. Key industries served include Oil & Gas, biogas, manufacturing, food & beverage, and renewables.

In the Oil & Gas sector, OxyHound is instrumental in measuring trace O2 levels in various operations, from VRUs to Enhanced Oil Recovery processes. It is also beneficial in manufacturing sectors like fiber optic production, annealing furnaces, and more. Additionally, it’s well-suited for renewable energy applications, including bio-gas and ethanol production.

OxyHound excels in environments with contaminants, such as H2S, CO2, and H2. Its maintenance-friendly design eliminates the need for electrolyte changes or membrane maintenance. This makes it an advantageous replacement over older technologies like paramagnetic analyzers, electrochemical cells, and in some instances, zirconia and Tunable Diode Laser (TDL) technologies.

The OxyHound analyzer operates using advanced optical quench luminescence, tailored for precise oxygen measurement in process streams. This technology hinges on the phase modulation of an oxygen-specific luminophore’s luminescent decay time, enabling accurate calculation of oxygen’s partial pressure. OxyHound measures the phase shift and intensity variation between the excitation light and the fluorescent response. From these measurements, the oxygen concentration is precisely calculated by the on-board computer in the analyzer in real-time.
