Technical Advantages Switchable floating and earthing mode All CS potentiostats/galvanostats can switch between the floating and earthing modes, and this strategy is beneficial for studying electrochemical systems in which the working electrodes are intrinsically ground, such as autoclaves, in-site concrete structures and multi-working electrodes requiring isolation, etc.High-bandwidth EIS With the help of built-in digital FRA and arbitrary signal generator, as well as the high input impedance (1013 W), the CS potentiostat is particularly suitable for EIS measurements of high-impedance systems (such as coating, membrane, concrete, etc.) Based on the DC bias compensation technique, CS potentiostats can conduct EIS tests under different charge/discharge states of batteries, making them suitable for ultra-low resistance systems, such as power batteries, fuel cells, water-splitting equipment, etc.Multiple electrode configurationsCS potentiostats support 2-, 3-, or 4-electrode configurations and can measure the galvanic current via built-in zero resistance ammeter circuits.User-defined sequence testCS Studio 6.0 for Windows software supports user-defined sequence tests ("combination test"), which can facilitate automatic testing according to user-defined experiment sequences. Sequence Test: corrosion tests Power boosterThrough CS2020B/CS2040B/CS2100B booster, the CS potentiostats can extend their output current up to ±20A/40A/100A, meeting the growing requirements in fuel cells, power batteries, electroplating etc.The compliance voltage of single-channel potentiostat can be customized(±30V),suitable for carbon/nitrogen electrochemical reduction.CS potentiostats can work with a CST520 arrayed electrode mapper to study the non-uniform corrosion of metal samples under deposits, coatings and anti-rust oils.Software development kit (SDK)All CS potentiostats run under the control of CS Studio 6.0 for Windows (CSS 6.0). The CSS6.0 supports third-party languages, such as LabVIEW, C, C++, C#, VC, Python and others. Some API general interfaces and development examples can be supplied with the CS potentiostats. Through the SDK, customers can implement user-defined test methods.
