This setup enables the calculation of the hydrogen diffusion coefficient in metals and the measurement of hydrogen flux. Technical Advantages 1. Impedance (EIS) The Corrtest potentiostat utilizes a correlation integral algorithm along with a dual-channel over-sampling technique, providing robust resistance to interference. This makes it highly effective for EIS measurements in high-impedance systems (>10⁹Ω), such as coatings, concrete, and similar materials.

Polarization Curve A Tafel plot can be generated, allowing users to set the anodic reversal current (the current at which the passivation film breaks down) on the cyclic polarization curve. This helps in determining the material's pitting potential and protection potential, which are crucial for evaluating its susceptibility to intergranular corrosion. The software employs non-linear fitting to analyze the polarization curve, providing a rapid assessment of the material's corrosion resistance and the effectiveness of inhibitors.
