Description
This EIS corrosion package includes everything you need to get started with corrosion measurements.
The included instrument is the EmStat4S HR, which is a small research-grade potentiostat. The EmStat4S HR supports all common electrochemical techniques used for corrosion analysis. These techniques include Electrochemical Impedance Spectroscopy (EIS), Potentiostatic Polarization, Linear Polarization, Cyclic Polarization, Corrosion potential measurements as well as applying a constant potential and measuring the open circuit potential (EOC). It has a wide range of current ranges and supports a maximum currrent up to 200 mA for determining corrosion rates. 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.

standard cables were used. Please note that the true limits of an impedance measurement are influenced by all
components in the system, e.g. connections, the environment, and the cell.
Software
PSTrace corrosion mode
PSTrace for Windows has a special Corrosion mode, in which it provides support for all common corrosion techniques and device functionalities. With a smooth simple interface, showing only the applicable controls, PSTrace is suitable for all levels of user experience. Functions include:
- Tafel analysis
- Determine Corrosion Potential and Current
- Circuit fitting
- Determine Corrosion Rate
Tafel plot analysis
The exponential relationship between the applied current at a platinum surface and the potential plotted in a graph is known as a Tafel plot. PSTrace helps you fitting a Tafel plot and deriving the corrosion current and corrosion rate.
Circuit fitting
PSTrace supports Equivalent Circuit Fitting. Drawing your circuit and fitting your data has never been easier. The interface allows you to quickly draw or change the circuit design. The circuit and fitted data are automatically saved with your .pssession data file.
The circuit editor can be used in different modes;
- Edit mode; draw the circuit or type CDC circuit
- Fit mode; fit the EIS data on the circuit
- Simulation mode; run simulations on circuits
