TECHNICAL ADVANTAGES
1. Impedance (EIS)
CS310potentiostat 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.). It can also be used to obtain Mott-Schottky curve and differential capacitance curve. During test, the software can display real-time open circuit potential (OCP) without entering.

2. Polarization curve
It can complete linear polarization curve and Tafel plot measurements. 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 uate 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.

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. Through noise spectrum, we can uate 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.
