Auto-Titration & KF Analysis

Description

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.The 12 series of Automatic Titration systems offers the following modes of analysis:INCREMENTAL – This method operates with a user selectable fixed dose and fixed intervals until the end point is detected or volume limit is reached.EQUILIBRIUM – This is the Universal and Dynamic Titration. In this titration the dose and time automatically are tuned to the titration trend with evaluation of the end point.pH CUT OFF/STAT – in pH cut off mode the end point is determined in a pre-selectable pH window. In pH-STAT mode the pH value is maintained until the pre-selected time interval is reached.
