TD-500 D

TD-500 D featuring the least expensive, lightest, smallest, easiest to use, most accurate and most repeatable device on the market for measuring crude oil and condensates in produced water, de-salter tail water, tank bottoms, cargo heaters, or anywhere that crude oil comes in contact with water.

Turner Designs Hydrocarbon Instruments has developed a revolutionary Bench-top method to measure oil-in-water that uses NO-SOLVENT!!! The advantages are significant in that we have eliminated the health and safety hazards of transporting, handling and disposing of solvents commonly used in the field for oil-in-water analysis. Along with safety, the method eliminates operator error associated with precision liquid measurements during the analysis process. This new method is designed to be compatible with our TD-500D hand held oil-in water analyzer. It is a robust method using a simple surfactant instead of solvent, with unprecedented accuracy and repeatability.


  • Measures all oils including the heaviest of crudes to condensates up to 50 °API and refined diesel range oil, lube oils, and heavy fuel oils in water.
  • Measures dispersed (free) oil independent of WSO (Water Soluble Organics).
  • Unaffected by suspended solids.
  • Performance independent of process temperature.
  • Independent of lag time between sample gathering and analysis.
  • Precision sample volume not required.
  • No acid required.
  • Complete analysis in less than 10 min.
  • No solvents required, non-flammable, transport on any air carrier.
  • Measurement range from below 1ppm to over 10,000ppm without dilution.
  • Easy calibration with crude oil standards or correlation to other methods.
  • Portable, hand held, < 1lb.
  • Measures WSO independent of dispersed oil.
  • No interference from methanol.
