CS120 Potentiostat contains a fast digital function generator, high-speed data acquisition circuitry, a potentiostat. 
Model CS120 is the simplest model. Only potentiostat is integrated. No galvanostat. It’s suitable for those who have low budget and just want to do the most basic experiments such as CV, LSV, OCP.

                                                                   SOFTWARE FEATURES
CS studio software provides users a versatile smoothing/differential/ integration kit, which can complete the calculation of peak height, peak area and peak potential of CV curves.

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.
CS Studio software can achieve real time saving of the measuring data. The data can be automatically saved even in case of sudden power off.
CS studio kit has a built-in versatile timing policy for combined measurements, which can facilitate the automation of experiments and save time.  
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.
