The Solartron Analytical 1287A potentiostat/galvanostat is a high accuracy, wide bandwidth instrument which offers a range of ac/dc test capabilities. (AC requires a frequency response analyzer)
Measurement Integrity:
Central to the measurement capability of 1287A are two high resolution digital voltmeters which provide simultaneous voltage and current measurements.
Using Solartron Analytical’s patented pulse width conversion technique, they have high accuracy, stability and linearity throughout the entire range of the instrument.
The 1287A has excellent measurement resolution and accuracy down to 1μV for the reference electrodes and 1pA for the working electrode, which makes it an ideal choice for measurements where signal levels are extremely low.
The 1287A uses floating measurements on all connections: it is equally at home measuring corrosion rates on grounded oil pipelines as it is in the laboratory. For safety reasons, it is often necessary to ground laboratory equipment such as fuel cells and autoclaves, a major problem if your instrumentation is not capable of floating measurements.
The 1287A offers complete flexibility for cell connection: 2-, 3- or 4-terminal measurements can be made with equal ease.
2-terminal techniques for general materials/electrochemical testing
3-terminal techniques for corrosion/coating applications
4-terminal techniques for accurate characterization of batteries/fuelcells, enabling lead resistance and impedance effects to be minimized
Applications: The 1287A works with 1260A Impedance Analyzer or any of the Solartron Analytical Frequency Response Analyzers (FRA) to provide wide bandwidth Electrochemical Impedance Spectroscopy (EIS).
Electrochemistry Software:
CorrWare and ZPlot packages are specifically designed to run a wide range of electrochemical tests including:
