Pyxis oil in water sensor

Pyxis HM-500 Series

Measures for oil in water at a range of 0-10ppm with automatic compensation for colour & turbidity interference

The fluidic & optical arrangement of the HM-500 is 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 colour/turbidity interference & fouling and can also be very difficult to clean.


  • Provided with the ST-001 inline tee assembly 3/4inch FNPT/CPVC
  • Offers a 304 stainless steel 3/4inch FNPT variant for harsh applications
  • Submersion adapter kit (MA-102S) available for CPVC submersed applications
  • Unique design with extra photo-electric components
  • Automatically compensates for colour & turbidity contamination
  • Flexible/advanced communication 4-20mA output & RS-485 output
  • Connectible to any conventional microprocessor controller, PLC or DCS
  • Bluetooth® enabled when used with the MA-WB or PowerPACK series of adapters
  • Bluetooth wireless interface via uPyxis® app
  • uPyxis® allows for sensor cleanliness diagnostics, calibration & configuration
  • uPyxis allows users to write calibration to sensors for a variety of oils as ppm
  • Lower cost & higher accuracy vs conventional UV fluorometers for oil in water


Typical applications

  • Heat exchanger leak detection
  • Oil tank leakage detection
  • Intake water monitoring (UF & RO feed water)
  • Re-injection water monitoring
  • Industrial wastewater monitoring
  • Marine discharge monitoring
  • Plant runoff / storm water monitoring
