1285A DC Potentiostat Galvanostat

315 1285
In the world of electrochemical research, Solartron Analytical has established an unrivaled reputation for providing impedance measurement instruments of the highest quality and reliability. The introduction of the 1285A Potentiostat affords scientists specializing in DC electrochemistry the benefits of Solartron Analytical’s superior technology in a comprehensive yet cost-effective package.

The 1285A combines Solartron Analytical measurement hardware with highly respected CorrWare for Windows™software. In conjunction with a standard PC, a complete spectrum of DC measurement techniques can be applied with unprecedented ease.

Complex experiments can be set up, stored and repeated at the click of a mouse. Using the scanner facility, multiple sequences can be repeated indefinitely without further intervention. Data can be analyzed in a wide variety of display formats, and you can even calculate corrosion rates using automatic Tafel curve fit routines.
