ASTM D2272 / SH/T 0193 Compliant Rotating Pressure Vessel Oxidation Tester (RPVOT)
Product Overview
The A1100 Lubricating Oil Oxidation Stability Tester is a high-precision laboratory instrument designed for determining the oxidation stability of turbine oils and lubricating oils with similar compositions. It adopts the internationally recognized Rotating Pressure Vessel Oxidation Test (RPVOT) method, which evaluates the resistance of lubricating oils to oxidation under accelerated conditions of high temperature, oxygen pressure, and catalytic environment.
Oxidation stability is a critical performance indicator for lubricants, especially in long-term industrial applications such as power generation turbines, hydraulic systems, and heavy-duty machinery. The A1100 provides accurate and repeatable data to help laboratories and manufacturers evaluate oil quality, predict service life, and optimize formulation performance.
This instrument is widely used in petroleum refineries, chemical plants, power stations, research institutes, quality inspection agencies, and industrial laboratories. With advanced automation and intelligent control, the A1100 ensures stable operation, high efficiency, and reliable test results, making it an essential tool for modern oil testing laboratories.

Working Principle
The A1100 operates based on the Rotating Pressure Vessel Oxidation Test (RPVOT) principle. A measured quantity of lubricating oil is placed in a sealed pressure vessel together with distilled water and a copper catalyst coil. The vessel is then filled with oxygen to a specific pressure and immersed in a constant-temperature heating bath.
During operation, the vessel rotates at a constant speed, ensuring uniform reaction conditions. As oxidation proceeds, oxygen is consumed, resulting in a gradual decrease in internal pressure. The instrument continuously records pressure changes over time and generates a pressure-time curve.
When a significant pressure drop occurs, the system automatically detects the oxidation induction period, which represents the oxidation stability of the oil sample. A longer induction period indicates better oxidation resistance and higher oil quality.
This method provides a reliable simulation of real operating conditions in turbines and industrial lubrication systems, making it a widely accepted standard test in the petroleum industry.
