SH108A Hydraulic Oil acid value tester

The acid value of oil products is an indicator for measuring the content of acidic substances in petroleum products, expressed as the milligrams of potassium hydroxide required to neutralize 1 gram of oil sample (mgKOH/g). It is a key basis for judging the degree of oxidation and deterioration of oil products, the corrosiveness of equipment, and whether replacement is needed. By measuring the acid value, the aging of insulating materials and the corrosion of metal parts of power equipment such as transformers and steam turbines caused by excessively high acidity in oil samples can be prevented in advance, ensuring the long-term safe and stable operation of the equipment.

The determination of acid value in oil products is widely applied in the quality control of products in petroleum refineries, the monitoring of equipment oil in power plants, and the oil analysis and research in scientific research institutions. It is an indispensable testing item in the oil quality inspection process.

The SH108A fully automatic oleic acid value tester features a large blue LCD screen display, with a Chinese menu and unmarked keys, making operation intuitive and simple. It complies with the national standards GB/T264 "Determination of Acid Value of Petroleum Products" and GB/T4945 "Determination of Acid Value and Base Value of Petroleum Products and Lubricants (Color Indicator Method)". Based on the principle of titration neutralization, it automatically completes liquid injection, titration, stirring and determination of the endpoint of neutralization titration under the control of a microcomputer. The measurement can be completed within 7 minutes. And it can automatically print and record the results. The instrument uses specially designed reagent bottles to hold the extraction liquid and neutralization liquid, which can isolate the air to prevent the evaporation of reagents and the interference of carbon dioxide, while protecting the safety of the operator. It can also choose to test 1 to 6 oil samples at a time, meeting the needs of diverse sample detection.
