This EIS Plus Corrosion Package includes everything you need to get started with corrosion measurements.

The included instrument is the PalmSens4 which is a USB and battery-powered Potentiostat, Galvanostat, and Electrochemical Impedance Spectroscopy (EIS) analyzer. The PalmSens4 has a large potential range (-10V to 10V) and current range (100 pA to 10 mA) with a high resolution and low noise. This instrument is a complete laboratory instrument but its compact and rugged design makes it also ideal for fieldwork.

PalmSens4 allows for a wide range of corrosion analysis methods; polarization curves to extract the Tafel slopes, corrosion rates, corrosion current, apply a current to the surface for electroplating, deposit films, or force corrosion to happen. Additionally, you can perform EIS (Electrochemical Impedance Spectroscopy) from 0.1 µHz to 1 MHz, which will allow you to extract the coating resistance, the polarization resistance, the pore resistance, the coating capacitance, water uptake of a coating and to estimate the time to failure (TTF). The instrument comes with PSTrace5 software which allows for different corrosion analytical techniques for automatic or manual analysis.

Together with our Corrosion Handbook and the Corrosion Cell Kit, it makes a good combination to get going with electrochemical corrosion studies.

Electrochemical Impedance Spectroscopy (EIS)
EIS allows observing: changes on surface properties, pitting corrosion, water uptake of a coating, estimation of delamination area and estimation of time to failure
