Specification for Dual Analogue Potentiostat

Features
A low noise, low current, two channel analogue potentiostat powered by rechargeable batteries has four manually selectable gains. It includes an internal settable applied voltage with LCD and an analogue input for an external settable applied voltage. The currents are measured via three +/- 5V outputs, two for each channel and one for the difference. Four current ranges from 1nA/V to 1μA/V are included with three filter options.
It can be supplied with higher custom current ranges from 1μA/V to 1mA/V and/or with electrode leads and connectors for 1mm microelectrodes.
