Large currents and reliability, all you need for batteries and more..

Model 2550 is the big-brother of Model 2551 with increased maximum current capability on a single channel.

It is very popular for material science and batteries characterization, thanks to its stability and accuracy. New features make it much more attractive, among them positive feedback control, IR compensation and manual or automatic current ranging.
