Acid Number Tester AAT-A12
The Acid Number Tester AAT-A12 is an advanced system driven by a microprocessor unit, ensuring precise automation. With a potential measurement range spanning from 0 to 1800.0 mV and an acid number measurement range of ≥0.05 mg KOH/g, it operates on the potentiometric titration principle. By recording electrode potential titration and volume, it identifies the equivalence point and corresponding titrant volume, enabling the determination of sample pH value. This versatile unit accurately assesses acid values in transformer oil, turbine oil, anti-oil, diesel, gasoline, and other petroleum products. It supports various protocols including Standard Determination of acid number and ASTM D664-2011 for Determination of acid number in transformer and turbine oils in service (BTB).
