Simultaneous Measurements


You can run a same experiment for each channel at the same time. Set the same parameters for each experiment once and run all independently. It's especially useful when you have many samples for one single test.

Simultaneous Measurements

You can also choose different techniques in each channel. Set the parameters for each experiment one by one, and run each experiment independently. As is shown in right picture, EIS, Galvanostatic charge & discharge, Cyclic Voltammetry, and polarization curve test are tested.

Technical advantages


1. Impedance (EIS)

The potentiostat applies correlation integral algorithm and dual-channel over-sampling technique, and has strong anti-interference ability. It is suitable for EIS measurements of high-impedance system (>109Ω, such as coating, concrete etc.).


2. Polarization curve

Tafel plot can be obtained. The user can set the anodic reversal current (passivation film breakdown current) of the cyclic polarization curve to obtain material’s pitting potential and protection potential and evaluate the its susceptibility to intergranular corrosion. The softwa

re uses non-linear fitting to analyze polarization curve, and can make fast evaluation of material’s anti-corrosion ability and inhibitors.

3. Voltammetry

Linear Sweep Voltammetry (LSV), Cyclic Voltammetry (CV), SCV, SWV, DPV, NPV, ACV, Stripping voltammetry etc. It integrates calculation of peak area, peak current and standard curve analysis.

4 Electrochemical Noise

With high-resistance follower and zero-resistance ammeter, it measures the natural potential/current fluctuations in corrosion system. It can be used to study pitting corrosion, galvanic corrosion, crevice corrosion, and stress corrosion cracking etc. Based on calculation of noise resistance and pitting index, it can complete localized corrosion monitoring.

5. Full floating measurement

Full-floating mode be used for autoclave electrochemical measurements, on-line corrosion monitoring of metallic components under the ground (rebar in concrete, etc.)


6. Software development kit (SDK)

  We are able to provide API functions and development examples, which facilitates some users’ requirements for secondary development and self-defined measurements. We can provide .dll file.


Software Features


Cyclic voltammetry: CS studio software provides users a versatile smoothing/differential/integrationkit, which can complete the calculation of peak height, peak area and peak potential of CV curves. In CV technique, during the data analysis, there is function of selecting exact cycle(s) to show.

Tafel plot and corrosion rate:

CS studio also provides powerful non-linear fitting on Butler-Volmer equation of polarization curve. It can calculate Tafel slope, corrosion current density, limitation current, polarization resistance, corrosion rate. It can also calculate the power spectrum density, noise resistance and noise spectrum resistance based on the electrochemical noise measurements.

Battery Test and analysis


EIS analysis: Bode, Nyquist, Mott-Schottky plot

During EIS data analysis, there is built-in fitting function to draw the custom equivalent circuit.

Real time saving of data: The data can be automatically saved even in case of sudden power off.


Combination test: it can facilitate the automation of experiments and save time. With the unique function of combination test, you can choose several techniques, and set the wait time, the start time, and the cycles. Choose the experiments you want to run. Then you can make auto measurement of the set experiments as you want without having to wait in the lab. This function is especially useful if you have multi experiments to run and save your time greatly.
