The content index of acidic substances in transformer oil, expressed as the milligrams of potassium hydroxide required to neutralize 1 gram of oil sample (mgKOH/g), is an important basis for judging the oxidation degree, corrosiveness of the oil and whether it needs to be replaced. By measuring the acid value, the aging of insulation materials and the corrosion of metal parts caused by excessive acidity of the oil can be prevented, ensuring the safe operation of power equipment such as transformers and steam turbines.
The SH108 transformer oil acid value tester features a large blue LCD screen display, a Chinese menu and unmarked keys, making operation intuitive and simple. It complies with the national standards GB/T 264 "Determination of Acid Value of Petroleum Products" and GB7599 "Determination of Acid Value of Transformer Oil and Turbine Oil in Operation (BTB Method)". Based on the principle of titration neutralization, it automatically completes liquid injection, titration, stirring and endpoint determination under the control of a microcomputer. The measurement can be completed within 7 minutes and the results can be automatically printed. This instrument supports testing 1 to 3 oil samples at a time. The reagent bottles can be isolated from air to prevent reagent evaporation and interference from carbon dioxide, while also protecting the safety of the operator.
