2550 - 2551 - 2553

2550 - 2551 - 2553 - Potentiostat Galvanostat

2550, 2551, 2553The new 255X series has been designed by Amel, using our 50-years-old experience, to rise and redefine the standards in the electrochemistry world. Reliability and performance make this new family of instruments the perfect choice for the most demanding application in the electrochemical research:

  • biochemical samples
  • analytical studies
  • corrosion tests
  • battery testing

All models ( 2550, 2551, 2553 ) offer several new features which makes it very attractive for high research laboratories: positive feedback control, fast transient response, current auto-ranging or manually, iR compensation, current mode interrupt.

A powerful managing software is delivered with any instrument, and an optional build-in frequency response analyzer provide fully integrated DC and EIS analysis in the range from 10µHz to 1MHz.
