Traditional manually controlled Potentiostats, Zero Resistance Ammeters and Sweep Generators still have a vital role to play. We have heard it said quite frequently, “I did my best work with a manual Potentiostat”. There is good reason for this. The raw experience of controlling an electrochemical cell by hand, gives the user a real feel of the nature of the cell being monitored, this in turn helps give the user a good understanding of Ohms Law, R=V/I and its application to electrochemical cells.

When listening to a highly complex and mathematical lecture based on data obtained by an automated Potentiostat, ex manual instrument users will always have that raw practical experience tucked away in their brains.

For instance with a manual system, a user can get a feel of the reaction time of the cell to both a cathodic and anodic polarisation. A different response time will have implications for AC Impedance tests that assume the response time is the same in both the anodic and cathodic directions.

ACM produces three types of manual instruments. These are the Research Potentiostat, Zero Resistance Ammeter and Sweep Generator. All instruments are fully floating and have buffered outputs that isolated the cell from low impedance measuring devices. A handy water resistant step-by-step manual guides the user through the setting up procedures for these instruments.

Potentiostat

potentiostat

In particular, the Research Potentiostat is recommended as a “must have” instrument for any laboratories that use Potentiostats. It can be configured as a two or three electrode Potentiostat, a Zero Resistance Ammeter and a Galvanostat.

Options:

      • Battery Option
    • 325mA
    • 1 Amp
    • 2 Amp

Zero Resistance Ammeter (ZRA)

ZRA (Zero Resistance Ammeter)

Many users like the single function Zero Resistance Ammeter. It is very simple to use and ideal for testing simple galvanic couples. Having a meter on the front makes it easy to monitor the Galvanic Current visually every few hours.

Sweep Generator

Sweep Generator

The Sweep Generator is typically used via the external input of the Research Potentiostat. A single Sweep Generator can control more than one Potentiostat at any one time. This makes it ideal for slow sweeps or multiple channel work where an automated system may be too expensive..
