System Highlights
Interface 5000E Potentiostat
The Interface 5000E potentiostat is designed for cell-level testing of various energy storage and conversion devices and includes capabilities for monitoring both half cell voltages in addition to the whole cell voltage during an experiment.
Dual Electrometer
A second electrometer gives you the ability to monitor both half cells in a typical three electrode setup. You can monitor both the anode and cathode in addition to the entire cell in charge/discharge experiments and EIS experiments.
Accuracy Contour Plot
The accuracy contour plot provides a detailed look at the performance you can expect from your instrument in real-world situations. The results include the cell cable. Accuracy contour plots are important because they let you compare the performance of different manufacturers to ensure you are getting the best possible measurement.
