Various engineered RULER™ Test Solutions allow you to test many different types of oils and applications. Our consistently high quality test solutions ensure high instrument precision and repeatability. The RULER Test solution vials (7ml glass vials filled with 1g of sand and 5ml of the specified formula) are prepacked in a pack of 24 units.
RULER™ provides critical information on the health of your lubricant.
Discover oxidation earlier than with any other technologies.
The RULER™ 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.
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™ 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).
Field Tested. Industry Supported.
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).
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.
