The HM-500 series measures oil in water (ppm) via UV-fluorescence, compensating for color/turbidity (up to 150 NTU). It ensures accuracy, easy cleaning, and wireless diagnostics.

About

The Pyxis Lab® HM-500 series of inline fluorometer sensors measure the concentration of oil in water, read as ppm Marine Crude-Offshore Oil. The sensors utilize an LED sourced UV-fluorescence methodology at 365nm wavelength & 410/470nm excitation. Our HM-500 series of sensors are uniquely designed with extra photo-electric components that also monitor the color & turbidity of the sample water. This proprietary feature enables the HM-500 series to automatically compensate for color and turbidity in the water sample eliminating interferences commonly associated with real-world waters, up to 150NTU. These sensors have a short fluidic channel and can be easily cleaned.

The fluidic & optical arrangement of the HM-500 series are designed to overcome short comings associated with other fluorometers that have a distal sensor surface or a long, narrow fluidic cell. Traditional inline fluorometers are susceptible to color/turbidity interference & fouling and can also be very difficult to clean. These unique features provide the HM-500 series with a level of accuracy far greater than conventional inline oil in water sensors & enable users to conduct wireless inline sensor cleanliness diagnostics as a predictive measure via the uPyxis® for mobile and desktop devices.
