Oxidation stability is a critical performance indicator for turbine oils and other lubricating oils. The test evaluates the resistance of lubricating oils to oxidation under accelerated conditions. The sample is placed in a rotating pressure vessel and exposed to oxygen at elevated temperature, allowing rapid evaluation of oil oxidation resistance.

This ASTM D2272 Oxidation Stability Tester is primarily used for assessing the oxidation stability of new and in-service turbine oils with the same base oil and additive composition at 150°C. It can also be used for rapid evaluation of oxidation stability of new mineral insulating oils containing antioxidant additives such as 2,6-di-tert-butyl-p-cresol or 2,6-di-tert-butylphenol at 140°C.

The system adopts a modern microprocessor control platform with automatic temperature regulation, oxygen charging, pressure monitoring, and real-time data recording, ensuring reliable and automated oxidation stability testing.

The ASTM D2272 Oxidation Stability Tester is suitable for evaluating oxidation stability of:

• Turbine oils
• Hydraulic oils
• Industrial lubricating oils
• Mineral insulating oils containing antioxidants

Typical application environments include:

• Lubricant manufacturing plants
• Petroleum refineries
• Power generation facilities
• Oil analysis laboratories
• Research and quality control institutions

The instrument automatically performs the entire oxidation stability testing process including temperature control, oxygen charging, pressure monitoring, and test result recording.

The instrument adopts a metal bath design compliant with ASTM D2272, eliminating the need for silicone oil bath media and reducing maintenance requirements.

Two independent testing positions allow simultaneous operation, significantly improving laboratory testing efficiency.

A high-precision pressure sensor continuously monitors the internal pressure of the oxidation vessel and records the pressure curve during the test.

The instrument automatically identifies the oxidation induction point and terminates the test after the endpoint is reached.

The system records and displays the pressure change curve during the entire oxidation process, allowing easy observation of oxidation behavior.

Up to 10,000 test results can be stored in the internal memory, enabling convenient historical data retrieval.

The instrument can be connected to a computer via USB interface for data export and laboratory network management (optional).

This Oxidation Stability Tester complies with the following standards:

• ASTM D2272 – Standard Test Method for Oxidation Stability of Steam Turbine Oils by Rotating Pressure Vessel
• SH/T 0193 – Determination of Oxidation Stability of Lubricating Oils (Rotating Oxygen Bomb Method)
