HGSZ221 Automatic Acid Value Tester

HGSZ221The fully automatic acid value tester is based onGB/T 28552reachGB/T 264Standard design and development, suitable for acid value analysis and measurement of samples such as transformer oil, turbine oil, and fire-resistant oil. Through the comprehensive application of mechanical, optical, and electronic technologies, automatic functions such as sample weighing, heating reflux, titration, determination of titration endpoint, and printing of measurement results can be achieved. Widely used in fields such as electricity, chemical industry, and environmental protection.
