HM703 Automatic Oil Acid Analyzer Operation Video
Product Overview & Application Scenarios

The HM703 Automatic Oleic Acid Analyzer features user-friendly operation and an aesthetically pleasing design. Employing fully automated digital computer control, the instrument utilizes acid-base neutralization reaction chemistry as its fundamental analytical framework. Combined with proprietary background derivation and blank endpoint determination logic, it achieves both precision and accuracy at an ideal level.
Application Areas
1. Energy Industry:
Power plants and substations conduct periodic sampling and testing of insulating oil within operational high-voltage transformers, current transformers, and voltage transformers.
2. Transformer Manufacturing:
Transformer manufacturers perform incoming inspection on newly procured insulating oil. Final inspection of internal insulating oil is required before transformer shipment.
3. Lubricant Industry:
Steel, chemical, and energy sectors conduct periodic testing of lubricants such as turbine oils and hydraulic fluids used in large rotating equipment (e.g., turbines, compressors, pumps).
4. Petrochemical and Refining Industry:
Refineries perform acid value analysis and testing on products including diesel fuel, biodiesel, and base oils.
