KN-titrate Automated Potentiometric Titrator
KN-titrate Automated Potentiometric Titrator is used for determination of Total Acid Number (TAN), Total Base Number (TBN), Mercaptan Sulfur and chlorine content of petroleum products, lubricants and transformer insulating oils. Titration is the fundamental chemical analysis procedure whereby the concentration of a chemical substance in solution is determined by reacting it with a measured amount of another chemical. The Auto titrator performs this analysis using a motor driven dispenser, stirred reaction vessel and electrodes which sense the completion of reaction by measuring the potential difference between two electrodes. Automatic Titration increases accuracy, repeatability and reproducibility as well as minimizing errors in calculation and documentation.
