Main features:
Adopting the patent of Swiss Wantong, Dosis^TMLiquid addition unit
Duosi's patented design^TMThe liquid addition unit can be directly installed on the top of the reagent bottle, which means that the liquid addition unit does not require additional workbench space. Based on a suitable interface adapter, the dispensing unit can be directly installed on any specification of reagent bottle. Duosi^TMThe system adopts the latest electronic and micro mechanical technologies. The replacement of the liquid addition unit can be completed in a very short time. The design of the transparent shell allows for clear visibility of any air bubbles that may exist inside the burette, facilitating timely elimination, while also allowing for real-time observation of the position of the driving valve. The flushing and preparation of the liquid addition unit are fully automated and do not require manual disassembly for cleaning.

Both 905/907 support DET dynamic titration, MET equivalent titration, and SET set titration
The 905 editable method supports KF volumetric Karl Fischer titration and STAT constant potential titration
The 907 type built-in method supports KF volumetric Karl Fischer titration and STAT constant potential titration
