Potentiostat / Galvanostat intermediate power 5A - 5V
The Materials M 515 is a high accuracy, high resolution intermediate power potentiostat / galvanostat.
A potentiostat is a control and measuring device. It comprises an electric circuit which controls the potential across the cell by sensing changes in its resistance, varying accordingly the current supplied to the system: a higher resistance will result in a decreased current, while a lower resistance will result in an increased current, in order to keep the voltage constant as described by Ohm's law.
As a result, the variable system resistance and the controlled current are inversely proportional.
Io is the output electrical current of the potentiostat
