The 12 series of Automated Titration performs the fundamental task of titration where the concentration of a chemical substance 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 the reaction by measuring the potential difference between two electrodes.<\/p>\n
