Features

Compact integrated design

• Easy to pick up to anywhere you need to, the host, stir, titration, reagent

• bottle holder are integrated with the shell.

• 7-inch color touch screen, inbuilt Android-based operating system,

• multi-status indicator light.

• The main unit is Splash-proof. And the titration base has the liquid drainage

• design to prevent liquid deposition and penetration.

• The reagent bottle has sealing cover, can fill the effective isolation

• adsorption material, to prevent any polluted by the air or the escaped odour.

• Zero-dead volume solenoid valve changing easily for PTFE burette.

Smaller body, higher performance

• Support MET, DET, EP and other titration modes, can finish acid-base, precipitation, nonaqueous,

• redox, complexation and other titration.

• With programmable liquid dispensing function, can set the liquid adding volume, liquid adding interval,

• liquid adding times, to prepare the solvent.

• Support the function of Custom formula editor, to let the complicated calculation’s results easily.

• All detailed titration nodes can be viewed, and the end point can be manually set and saved as

• associated data, reducing unnecessary repeated laboratory tests.

• Historical data can be viewed during testing, let the error correction in time.

• Multiple self-inspecting function, pH electrode calibration, burette calibration.

• The methods are programmable and storable, and can be one-click call out.

Perfect laboratory data security management

• Four levels of authority for ID, and each level ID’s authority is settable.

• E-Signature, Data exporting is tamper-proofing, and so on.

• Support password security setting, and also can set the passwords’ aging time.

• Support PDF or Excel formats data export,both list or detailed reports.

• Support dot matrix printer and wireless connection laser printer.

• Storage space: 4G

• With a multi-level retrieval function, you can quickly search the target data from the data base.
