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.

12系列自動滴定完成了滴定的基本任務，其中一種化學物質的濃度是通過與另一種化學物質的測定量反應來確定的。自動滴定器使用電機驅動的分配器、攪拌反應容器和電極進行這一分析，通過測量兩個電極之間的電位差來感知反應的完成。

The 12 series of Automatic Titration systems offers the following modes of analysis:12系列自動滴定系統(tǒng)提供以下分析模式：

INCREMENTAL – This method operates with a user selectable fixed dose and fixed intervals until the end point is detected or volume limit is reached.增量-該方法使用用戶可選擇的固定劑量和固定間隔，直到檢測到終點或達到體積極限為止。

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.?平衡——這是一種通用的動態(tài)滴定法。在這個滴定中，劑量和時間自動地隨著滴定終點的評價而調諧到滴定趨勢。

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. PH截止/ STAT -在pH截止模式下，終點可在預先選擇的pH窗口中確定。在pH-STAT模式下，保持pH值直到達到預先選定的時間間隔
