ZDDY-2008 automatic potentiometric titratorDetailed product description：

The ZDDY-2008 automatic potentiometric titrator adopts an electromechanical integrated structure design. The instrument is completely controlled by a microcomputer (MCU microprocessor) and operated by a mouse, achieving automation and visualization of the titration process and data processing. Different electrodes can be used for various titrations, such as acid-base neutralization titration, precipitation titration, oxidation-reduction titration, complexometric titration, and non-aqueous titration (such as determining thiol sulfur and acid value in petrochemical oils). The titration system is made of corrosion-resistant materials, with a long service life, high cost-effectiveness, practical software, suitable for multiple industry applications, especially for teaching and research in university laboratories.
