The SA-500P is an in-line probe Oil in Water analyser suitable for non-hazardous areas; it uses Deep UV Fluorescence to provide continuous accurate measurements of oil concentrations in water. The analyser detects a wide range of oils/ oil components such as fuel oils, condensates, lubricating oils, gear oils, BTEX, PAHs which are typically difficult with standard techniques as well as crude oils. The SA-500P is ideally suited for refineries, marine, industrial and waste-water oil in water monitoring.




  • Patented ultrasonic cleaning.
  • Deep UV Fluorescence.
  • Configurable measurement ranges (0-10 ppm, 0-100 ppm […] up to 0-100,000 ppm).
  • Measurement repeatability ±1% of full scale.
  • Remote management and diagnostics.
  • Easy to install (no sample conditioning required).
  • Multiple communications options – 4-20 mA, HART, Modbus, Extended Ethernet.
  • Adaptive ultrasonic cleaning.
  • Optional hot insertion/ extraction.


  • No user required maintenance.
  • Consistent accurate performance.
  • No sample conditioning system required. Inserted directly in process pipe.
  • Can detect BTEX components.
  • Low Cost of Ownership (COO) with no routine maintenance required.
  • During process shut down, the analyser can be turned to standby mode through remote digital input. All signals are accessible remotely through Modbus/ Ethernet connectivity and 4-20mA.
  • With double block and bleed valve, probe can be inserted/ removed without process shut down.
