Fully automatic reagent metering/titration unit DT 10

Fully automatic reagent metering and titration for the DIN 38409 H 41 COD method. Reagent addition and titration of up to 12 simultaneous samples. Automatic draining of titrated waste solution. Simple user-friendly operation under MS Windows interface. Sample date can be stored and processed in MS Access.

Reagent delivery: Delivery of COD reagents in optimal timed intervals (IAW DIN) prevents sample overheating. Up to 30 separate syringe drive reagent modules can be controlled by the DT 10.

Titration: Freely definable "methods" such as end-point, equivalence, linear, dynamic and quasi-dynamic titrations may be programmed. Several password-protected user levels. Graphical output with first and second derivatives. Sample data to be printed is freely selectable. All national COD analysis procedures may be implemented as "methods".

Within the 330 × 220 mm working area, the DT 10 can be modified to access arrays consisting of various numbers and sizes of vessel. Useable for all reagent metering and titration applications.
