2553 High Voltage Potentiostat-Galvanostat
Potentiostat with large dynamic range
Model 2553 allows for experiments where a large compliance potential is required, along with stability of the measurement and long-time reliability. The new version offers positive feedback control, fast transient response, automatic or manual current ranging and IR compensation.
