ASTM D2272 RPVOT Tester Oxidation Stability Bath Lubricating Oils Equipment Product Description >>> The Rotating Pressure Vessel Oxidation Test (RPVOT) is a test that determines the oxidation stability of an oil. RPVOT measures the actual resistance to oil oxidation whereas the other tests detect oxidation that is already present in the oil. >>> RPVOT is a more proactive approach because you can respond to pending problems before permanent harm is done to the oil or machine. The test is ideal for large oil volumes with low makeup fluid requirements and also severe-duty applications. >>> The test is very expensive to perform routinely and is usually performed annually on very large oil reservoirs such as a steam turbine. Performance feature >>> The instrument adopts the advanced technology abroad, by PLC and touch screen (10 inches) combination control to automatically detect, calculate and record various data, the whole test process without personnel on duty, high degree of automation. >>> Metal bath structure design, instead of oil bath, no heating oil smoke, no complicated cleaning after the experiment. >>> The instrument has the dual function of automatic and manual oxygenation, and has the function of automatically judging the leakage of the projectile body. >>> Metal bath heating, with temperature overheating protection device. >>> At the end of the experiment, the instrument can automatically save the experimental results and print the experimental data. >>> Oxidation Stability Tester can be connected to LIMS system. >>> Equipped with electric winding machine, can make catalyst coil by itself.

The RPVOT test was never intended to be used to compare lubricant. One reason for this is that it is an imprecise simulation of an actual turbine oil in use. For example, the test accelerates the aging of the oil by using a copper catalyst; turbine oil formulators can therefore "cheat" the test by increasing the amount of copper passivators in the formulation. There is no practical benefit of doing this in real-world use. Q2: How Should RPVOT be Used? In an ideal world, RPVOT would simply be one of many used oil analysis test that are interpreted together. By trending RPVOT, MPC, UC, FTIR, ICP, RULER and other results, an overall picture of turbine asset health can be established. This can enable the oil to be drained at the right time. Q3: RPVOT vs RULER, Which is Better? When monitoring turbine oils, one of the questions we often get asked is whether the user can substitute RPVOT for RULER or vice versa. The short answer to this question is, No. Both tests measure or predict different things hence, one should not replace the other if the user is trying to identify a particular quality or quantity. In this blog, we will be exploring the differences between these two tests, when they should be used and why. Q4: Why is oxidation stability important? Oxidation stability is one of the most important quality parameters of edible vegetable oils. It determines their usefulness in technological processes as well as shelf life. In food chemistry, many methods are used to determine the oxidative stability of oils Q5: What determines stability of an
