The user can set the anodic reversal current (passivation film breakdown current) of the cyclic polarization curve to determine material's pitting potential and protection potential and evaluate the its susceptibility to intergranular corrosion. The software employs non-linear fitting to analyze polarization curve, and can make fast evaluation of material's anti-corrosion ability and inhibitors.Polarization curve of Ti-based amorphous alloy &stainless steel in 3%NaCl solutionVoltammetryIt can do the following electroanalysis methods: Linear Sweep Voltammetry(LSV), Cyclic Voltammetry(CV).It integrates calculation of peak area, peak current and standard curve analysis.LSV curve: mesoporous carbon material in 0.1M KOHCV curves of PPysupercapacitor in 0.5 mol/L H2SO4Electrochemical NoiseWith 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. Through noise spectrum, we can evaluate the inducement, growth and death of metastable pitting and crack. Based on calculation of noise resistance and pitting index, it can complete localized corrosion monitoring.Electrochemical noise of low-carbon steel in 0.05mol/L Cl-+0.1mol/L NaHCO3Full floating measurementCS150M workstation uses full-floating working electrode. It can be used for autoclave electrochemical measurements, on-line corrosion monitoring of metallic components under the ground (rebar in concrete, etc.)Software development kit(SDK)We can provide secondary development interfaces,API general interfaces and development examples, and can realize data call for Labview, C, C++, C#, VC and other program, which is convenient for secondary development and test methods customization.High current, high compliance optionsWith the CS2020B/CS2040B booster, the current can be boosted to 20A/40A, which meets the requirement in fuel cell, power battery, electroplating, etc Can customize the instrument to be 30V high compliance voltage, which meets the test requirement in low-conductivity solutions (organic system, concrete system etc), especially suitable for carbon and nitrogen reduction study.Real-time data storageExperiment data can be stored in real time. Even if the test is interrupted by a power failure, the data will be automatically saved. The data is compatible with Excel, Origin, and can be directly opened.
