PT-D2272-0193 Automatic Lubricating Oils Oxidation Stability Tester is designed and made as per SH/T0193 and ASTM D2272. It is suitable to determine oxidation stability of new or in service turbine oil, which has the same components (base oil and additive). It is also a rapid method for determining the oxygen stability of new mineral insulating oils containing 2, 6-Di-tert-butyl-p-cresol. It can check pressure, record test data, and calculate oxidation time for measured sample automatically. It can also end a test automatically. It can save test curves and test data automatically when show them on the display. The operators can print them out when needed. The test can be completed automatically without any human involvement after you start a test. This significantly lowers down the labor intensity of operators and highly improves the accuracy of test data. It is the best choice of companies for selecting an automatic instrument.
Main technical features
- This instrument is fully designed as per standard SH/T0193. It can automatically determine pressure, record data, calculate oxidation time and finish the determination.
- The test procedures can be done automatically. No need for human interference. The test precision is high.
- The test curves and results will be shown on the screen and can be restored and printed if needed.
