The acid value is an important parameter used to evaluate the oxidation condition, contamination level, and service life of petroleum products. An increase in acid value may indicate oil degradation, oxidation, or contamination, which can negatively affect lubrication performance and equipment reliability.

This Acid Value Tester adopts the reflux titration method, integrating automatic heating, boiling reflux, titration, endpoint detection, waste discharge, cleaning, and result printing into a fully automated testing process.

The system features an 8-inch color touchscreen, RGB color sensor, laser detection technology, and microcomputer control, ensuring high accuracy, good repeatability, and reliable operation.

It is widely used in power plants, petroleum laboratories, transformer oil testing facilities, inspection agencies, and research institutes.

The Automatic Acid Value Tester is suitable for determining the acid value of:

• Transformer oils
• Turbine oils
• Lubricating oils
• Hydraulic oils
• Light petroleum products
• Insulating oils Industrial oils

Typical application environments include:

• Power generation plants
• Petroleum refineries
• Transformer maintenance companies
• Oil analysis laboratories
• Inspection and certification laboratories
• Research institutes and universities

The instrument automatically completes the entire testing process including heating, reflux, titration, endpoint detection, result calculation, waste discharge, and cleaning.

The analyzer adopts the reflux method principle, ensuring accurate acid value determination in accordance with standard testing procedures.

An 8-inch Chinese and English color touchscreen provides convenient operation and menu-guided parameter input.

The detection system uses advanced laser components and a high-precision RGB color sensor for accurate endpoint determination.

A programmed heating bath automatically performs boiling and reflux operations, reducing manual intervention.

After each test, the instrument automatically discharges waste liquid and cleans the reaction bottle.

The analyzer can store up to 300 historical test records, allowing easy data retrieval and printing.

The housing is made of high-quality steel plate with electrostatic spray coating, providing good corrosion resistance and easy cleaning.

This Reflux Method Acid Value Tester complies with the following standards:

• GB/T 264 – Test Method for Acid Number of Petroleum Products
• GB/T 7599 – Determination of Acid Number of In-Service Transformer Oil and Turbine Oil (BTB Method)
• GB/T 258 – Test Method for Acidity of Light Petroleum Products
• GB/T 28552 – Determination of Acid Number of Transformer Oil and Turbine Oil
• ASTM D974 – Standard Test Method for Acid and Base Number by Color-Indicator Titration
• ASTM D664 – Standard Test Method for Acid Number of Petroleum Products by Potentiometric Titration

These standards are widely used for evaluating the acid value and oxidation condition of petroleum products.
