Overview
The Solartron Analytical 1287 Electrochemical interface is a high accuracy, wide bandwidth potentiostat/galvanostat which offers a full range of ac/dc test capabilities; when coupled with a frequency response analyzer.
Measurement Integrity
Central to the measurement capability of 1287 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 1287 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 1287 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 autoclaves, a major
problem if your instrumentation is not capable of floating measurements.
The 1287 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
