All oils eventually fail due to oxidation. In many applications such as turbines, hydraulics, compressors and aerospace, oxidation is the primary mode of failure. In these applications, the most important additive components are antioxidants. The patented RULER View™ uses Linear Sweep Voltammetry to quickly and accurately measure active antioxidants in lubricants and easily trend the depletion of these critical additives. With this information, you now know how much longer your fluid may last. We call this the oil's Remaining Useful Life (RUL).

The RULER View™ provides the full picture of a fluid's antioxidant additive health - it's a window into the health of your lubricant. This technology is a critical part of an effective condition monitoring program.
In the past, indirect measurements of the fluid's antioxidants were taken. Tests such as RPVOT (ASTM D2272) measure the oxidative stability of the fluid inferring antioxidant levels. This technology has been shown to be less effective in today's complex formulations employing hydro-treated mineral oils and new antioxidant technologies.

Other techniques to directly measure antioxidants such as infrared analysis (FTIR) often cannot provide the full picture. FTIR interpretation is complex and some additive components mask the critical antioxidant region.

•    Oxidation chemically degrades oils causing failures.

Applications & standards

Major equipment OEMs such as Siemens and GE recommend RULER as part of a condition monitoring program. Furthermore, most oil and additive manufacturers use the RULER™ technology as both a condition monitoring and research tool to gain further insights into their lubricant formulations. Be comfortable that your RULER™ technology is supported by industry. The RULER™ technology has received strong industry support over the last 15 years. There are four ASTM standards written around it (D7590, D6971, D6810 and D7527) as well as industry guidelines (DASTM4378 D6244 and DIN - VGB M416).

RULER™ Solutions are tailored to your application
  • Test result
    • Concentration of antioxidants in comparison to the fresh oil or Remaining Useful Lifetime
  • Result range    
    • 0 - 100%
  • Analysis of    
    • All kind of highly stressed oils and greases which contents antioxidants, for example turbine oils, oil for gears, compressors and gas engines, circular lubrication and heat carrier oil.
  • Brief description   
    • During sample preparation the antioxidants are separated from the oil by adding a solvent and a substrate. According the principle of voltametry a current-time-curve is measured. Position and area of the peaks characterise type and amount of the antioxidant additives. The remaining antioxidants are calculated by integration of the adequate peak areas in comparison to the fresh oil.
  • Statement    
    • The result is the concentration of antioxidants in relation to the fresh oil. Due to the fact that the antioxidants are continuously reduced during their lifetime, it`s possible to estimate the remaining lifetime of the oil. If all antioxidants are used, an increased oxidation of the oil takes place.The oil quality fall off dramatically and the oil is no longer able to provide it’s functionality.
