Organic heat carrier acid value automatic analyzer (potentiometric titration method)

Organic heat carrier acid value automatic analyzer (potentiometric titration method)Overview

This instrument uses the principle of potentiometric titration. By recording the electrode potential and titration volume during the titration process, the equivalent point and corresponding volume of the standard titration solution can be identified to determine the pH value of the sample. This instrument can accurately detect the acid value of petroleum products such as transformer oil, heat transfer oil, turbine oil, fire-resistant oil, diesel, gasoline, etc. The instrument meets the standardsResearch, design, and manufacture of GB/T 24747-2023 Safety Technical Conditions for Organic Heat Carriers - Acid Value of Organic Heat Carriers (Potentiometric Titration Method); Also applicable standards: GB/T7304 "Determination of Acid Value of Petroleum Products and Lubricants (Potentiometric Titration Method)", GB/T264 "Determination of Acid Value of Petroleum Products", GB/T7599 "Determination of Oleic Acid Value of Transformer Oil and Turbine Oil in Operation (BTB)", GB/T 18609 "Determination of Oleic Acid Value of Crude Oil"Determination of Acid Value by Potentiometric Titration Method "and ASTM D664" Standard Determination of Acid Value of Petroleum Products by Potentiometric Titration Method "
