Functional Features
Cyclic voltammetry and linear sweep: Current averaging, controlled – current method, ohmic drop correction, corrosion rate analysis, and Tafel curve analysis.
Chronoamperometry, chronopotentiometry, and chronocoulometry: 1 to 255 different potentials/current values and ohmic drop compensation can be set, allowing for at least 65535 cycles of measurement.
Mixed mode: At least 255 segments can define applied signals, including potential steps, current steps, potential sweeps, current sweeps, open – circuit potential, controlled resistance and resistance sweeps; real – time impedance measurement from 10 Hz to 250 kHz; all steps and sweeps can monitor resistance and capacitance simultaneously during potential and current measurements; the entire process can be finite or continuously repeated.
Electrochemical noise: With electrochemical noise measurement and analysis functions.
AC impedance measurement and analysis functions: Can perform controlled – potential or controlled – current frequency sweeps; Mott – Schottky curves; electrochemical frequency modulation EFM; frequency range from 10 μHz to 250 kHz.
Photoelectrochemical functions: Through software’s I~V curve fitting function, short – circuit current (Isc), open – circuit voltage (Eoc), maximum power point (Pmax), and fill factor (FF) and other relevant parameters can be calculated. Connect to the photoelectrochemical module for measuring solar energy materials’ light – modulated AC impedance IMPS/IMVS.
Can connect to a WIFI module to achieve wireless connection between computers and instruments; can remotely control equipment in the laboratory through the network in the office.
Batch processing functions: Users can freely combine multiple measurement procedures and automatically perform them in sequence.
Open – source programs: Provide open – source programs, allowing users to write various programs through different programming languages, such as C++, Delphi, VB, etc., and more conveniently remotely control instruments through LabVIEW software.
Has 2 analog signal input channels and 1 analog signal output channel.
