Single-channel potentiostat/galvanostat with EIS Model CS1350Pro consists of a DDS arbitrary function generator, a potentiostat/galvanostat and an FRA. With the help of built-in dual 24-bit Delta-sigma AD converters, it achieves excellent stability and high potential (1mV) and current(1pA) resolutions. With 40+ electrochemical techniques, CS1350pro has been widely applied in corrosion, energy, material and analysis electrochemistry.
CS1350Pro is an upgraded version of the conventional single-channel electrochemical workstation CS350M with outstanding stability and accuracy, advanced hardware, and fully functional software. Maximum current can be as high as ±5A (without any booster).

Corrosion Electrochemistry
CS potentiostats/galvanostats support a variety of electrochemical techniques for corrosion, such as OCP recorder, potentiodynamic, EIS, cyclic polarization (CPP), LPR, hydrogen diffusion test, zero resistance ammeter (ZRA), electrochemical noise (ECN), etc.
Due to their high input impedance(1013Ω), they are especially suitable for EIS measurement of high-impedance systems like coating, concrete, and pure water.

Electrocatalysis
Based on CV and LSV techniques, CS potentiostats can carry out long-term tests for ORR, OER, HER, and CO2 reduction, which is crucial for evaluating catalyst stability.
CS potentiostats can measure the half-wave potential (ORR) and overpotential (HER, OER) of catalysts and calculate the power density and energy density of Redox peaks.

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.
Multi electrode configurations
CS potentiostats support 2-, 3-, or 4-electrode configurations and can measure the galvanic current via built-in zero resistance ammeter circuits.
User-defined sequence test
CS 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
Sequence Test: Pseudocapacitor tests
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.
Real-time data storage
CSS 6.0 saves experimental data timely, even if the experiment is accidentally interrupted by a power failure or computer shutdown. CSS 6.0 supports several data formats compatible with Originpro and Microsoft Excel.
