Full Auto Acid Value Tester (potentiometric titration) for Transformer Oil
1. Summary
The transformer oil acid value tester adopts the potentiometric titration principle. Recording the titration
of the electrode otential and the titration volume, find out the equivalence point and corresponding titration
volume, and thus obtained the sample pH value. This instrument can accurately detect the acid value of
transformer oil, turbine oil, anti oil, diesel, gasoline and other petroleum products; Widely used in chemical
industry, electric power, oil and other industries, it's the ideal acid number tester of petroleum products.
