The BD-8J automatic potentiometric titrator adopts a mechatronic structure design. The instrument is completely controlled by a computer (PC) to realize the automation of the titration process. Different electrodes can be used for: acid-base neutralization titration, precipitation titration, redox titration, and complex titration. , non-aqueous titration (such as determination of basic nitrogen, mercaptan sulfur, acid value, base value in petrochemical oil products; acid value (acid value) in the food industry; acid value (acid value) in resins in the chemical industry), etc. This kind of titration, the titration system adopts an integrated precision exchange unit made of imported special materials, equipped with an anti-penetration titration head, and is resistant to perchloric acid corrosion. The instrument is more reliable, has a longer service life, and is suitable for applications in many industries.

Main Features
Universal microcomputer and operating system, special software English window interface, mouse and keyboard operation, human-computer dialogue, easy to understand.
Real-time display of potential curve (E-V), first-order derivative curve (dE/dV), titration volume (V), electrode potential (E), titration method, and titration results. The titration process is intuitive and clear.
Full titration process data browsing, powerful data processing functions, massive storage of titration curves, titration results, and titration process data. Detailed titration process data of samples can be saved as Excel files to facilitate future inquiries.
Experimental data, graphics, and results can be saved as word documents, which facilitates report or paper output and remote network query.
Automatically print curves, results and titration process data.
Dynamic equivalence point titration (DET), isovolumetric equivalence point titration (MET), preset endpoint potential titration (SET), preset endpoint pH titration (SPH), pH calibration and measurement, pH standard curve storage and import .
The titration curve can be moved and enlarged arbitrarily, which is more conducive to using graphics to accurately correct and process the results.
Fully automatic "end point" identification, effectively filtering out false "end points", and supporting multi-end point titration (no limit on the number of end points).
Mass storage of titration method templates, and supports editing and modification of method template parameters.
High-precision "end point" manual deletion or addition function.
Automatic cleaning, automatic fluid replenishment, and automatic fixed-value fluid replenishment.
