 Potentiostat - Galvanostat
 The new Potentiostat - Galvanostat model PG581 from Uniscan Instruments heralds the next chapter in the development of portable electrochemistry and corrosion instrumentation. The instrument is a compact and powerful hand-held potentiostat - galvanostat with remarkable performance and is at home either in the laboratory or as a user configurable instrument for field use. The design of the PG581 makes it ideally suited for the in field development of electrochemical sensor technologies, and as a cost effective portable electrochemical and corrosion analyzer.
The PG581 potentiostat - galvanostat is connected to a PC via its USB port in the laboratory for electrochemical experiments such as cyclic voltammetry, chronoamperometry and square wave voltammetry with unsurpassed ultra low noise performance. In addition you can now upload those same techniques directly to the PG581 to collect data in the field without a computer.
The PG581 also provides support for the routine electrochemical corrosion techniques such a LRP, Tafel and Potentiodynamic Polarisation in the laboratory or in the field.

Using the device connected to a PC for advanced experiments
In this mode of operation, the instrument is remotely controlled by a PC. Standard electrochemical and corrosion experiments can be executed. Advanced experimental protocols can easily be construction with the easy to use autosequencing routine. The experimental parameters and data display are implemented on the PC in a Windows™ software application which provides full, detailed graphs, and filing of data objects. The powerful macro programming facility provided in the software allows the definition of custom experiments, data manipulation and display.
UiEChem™ suite of electrochemical techniques including:
- Cyclic and linear voltammetry
- Square wave voltammetry
- Normal and differential pulse voltammetry
- Chronoamperometry and chronopotentiometry
- User definable experiments via macro programming
UiECorr™ suite of corrosion techniques including:
- ECorr vs Time
- Linear Polarization Resistance (LPR)
- Tafel
- Potentiostatic polarization
- Galvanoststic polarization
- Potentiodynamic polarization
- Zero Resistance Ammetry (ZRA)
- User definable experiments via macro programming
Using the device stand alone with internal rechargeable battery power
 In this mode of operation the PG581 can be programmed to perform a specific measurement technique via Windows™ software on a PC. The experimental technique and parameters are created with the UiEChemTM or UiECorrTM software and uploaded via the USB connection to the instrument. Disconnect the USB cable and the PG581 is ready to run the experiment at the push of a button.
For more complex routines the macro programming facility gives the user the ability to program an experiment in C++ and upload the routine to the PG581 for execution. The PG581 will then operate as a field based instrument, repeatedly performing the user’s defined measurement and analysis algorithm and storing the data.
Potentiostats have historically found use in the laboratory in a range of electrochemical and corrosion research. The PG581 allows the user to escape the confines of a laboratory based environment.
Also available for the Model PG581 is a generic base sensor for sensor development applications.
The sensors comprise a standard three electrode configuration with a carbon working and counter electrode and an Ag/AgCl reference electrode. These base sensors are available in multiples of 25, 50 or more, with a separately available screened sensor connector for easy connection to the PG581.
A range of available off the shelf or custom made direct sensor connectors makes the PG581 a truly portable device.
