Water contamination is common in industrial lubrication systems such as turbines, hydraulic systems, and circulating oil systems. Oils with poor demulsibility may form stable emulsions, which can lead to corrosion, oxidation, reduced lubrication performance, and equipment damage. Therefore, evaluating the oil-water separation performance of lubricants is essential for quality control and equipment maintenance.

This Oil Demulsibility Tester provides precise temperature control, stable stirring performance, and simultaneous multi-sample testing, ensuring reliable and repeatable test results for petroleum product laboratories.

The instrument is widely used in petroleum refineries, lubricant production plants, power generation facilities, chemical industries, railway maintenance departments, and research laboratories.

The Oil Demulsibility Tester is used to determine the water separation characteristics of petroleum products and synthetic fluids.

• Turbine oils
• Hydraulic oils
• Industrial lubricating oils
• Circulating oils
• Synthetic lubricants
• In-service turbine oils

Typical application environments include:

• Petroleum refineries
• Lubricant manufacturing plants
• Power generation facilities
• Chemical industry laboratories
• Railway maintenance departments
• Oil condition monitoring laboratories
• Research and quality control institutions

The instrument adopts a precision temperature controller with rapid heating and stable temperature regulation. The temperature control accuracy reaches ±0.1°C, ensuring reliable testing conditions.

The instrument is equipped with three independent test positions, allowing three samples to be tested simultaneously and improving laboratory productivity.

A high-quality stirring motor ensures stable stirring speed, low noise operation, long service life, and reliable performance throughout the testing process.

Internal components such as the heater and stirring paddle are made of corrosion-resistant stainless steel, ensuring long-term durability and resistance to laboratory chemicals.

The system features a high-brightness digital display, allowing operators to easily monitor the temperature and operational status during the testing process.

This Petroleum Oil Water Separability Tester is designed and manufactured according to the following testing standards:

• ASTM D1401 – Standard Test Method for Water Separability of Petroleum Oils and Synthetic Fluids
• GB/T 7305 – Petroleum and Synthetic Fluids — Determination of Demulsibility Characteristics
• GB/T 7605 – Determination of Demulsibility of Turbine Oils in Service

These standards are widely used in petroleum laboratories and lubricant testing facilities to evaluate the demulsibility performance of lubricating oils.
