2559 Portable Potentiostat-Galvanostat

The ultimate hi-resolution pH-meter

Rise up your experiment power

The portable potentiosat Model 2559, latest addition to AMEL series of potentiostats, has been designed to be used individually or transformed into a multipotentiostat. The power supply unit, Model 2560, is able to power up to eight 2559 & 2700 units simultaneously.

All units are controlled by VA Peak and ZPulse softwares, each one independently. The idea behind this system is the possibility to quickly detach one unit from the multi-system and use it alone with a small, single unit, power supply which is always provided.
