Donghua electrochemical workstation

The DH7000C electrochemical test system consists of the DH7000C electrochemical workstation (potentiostat / galvanostat / AC impedance analyzer) and DH7000C control & data analysis software. The workstation integrates four core modules: electroanalysis, corrosion, AC impedance and energy modules. It is widely applied in electrode process research, chemical power sources, electroplating, electrolysis, phase analysis, metal corrosion research, electrochemical protection parameter measurement and other fields.

Supports all conventional electroanalytical testing methods, including CV, LSV, CA, SWV, NPV, DPV, ACV, etc.

Covers full range of electrochemical tests for corrosion and protection research, including linear polarization resistance (LPR) and Tafel analysis to obtain parameters such as corrosion current, polarization resistance (Rp) and corrosion rate. Electrochemical impedance spectroscopy (EIS) tests under various polarization conditions are also available.

Equipped with potential control and impedance modules, it realizes constant voltage, constant current, constant resistance and constant power charge-discharge tests with freely combinable charge-discharge functions. It meets test requirements for lithium batteries, fuel cells, supercapacitors and other new energy systems, enabling real-time monitoring and analysis of electrochemical reaction mechanisms.

Compatible with multiple expandable power amplifiers and connectable to various external devices. Suitable for material performance studies, such as anti-corrosion coating evaluation, catalyst performance characterization, and performance testing of cathode and anode materials for lithium-ion batteries.

Compatible with various biological electrodes (enzyme electrodes, microbial electrodes, ion-selective electrodes and other modified electrodes). Applicable to biological enzyme catalysis, biological semiconductors, biofuel cells, biosensors, as well as biomedical testing, environmental monitoring, food and pharmaceutical analysis.
