1. 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 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.

2. Voltammetry
It can do the following electroanalysis methods: Linear Sweep Voltammetry(LSV), Cyclic Voltammetry(CV), Staircase Cyclic Voltammetry(SCV), Square wave voltammetry(SWV), Differential Pulse Voltammetry(DPV), Normal Pulse Voltammetry(NPV), AC voltammetry(ACV), Stripping voltammetry etc. It integrates calculation of peak area, peak current and standard curve analysis.

3. Electrochemical Noise
With high-resistance follower and zero-resistance ammeter, it measures the natural potential/currentfluctuations 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.

4. Full floating measurement
CS300 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.)
5. User-defined methods
CS300 workstation supports user-defined combination measurements. The user can set cyclic timing measurements of an electrochemical method or several methods.
We are able to provide API functions and development examples, which facilitates some users' requirements for secondary development and self-defined measurements.
