The XPOT potentiostat is a competitively-priced 4-quadrant potentiostat which can be used in connection with the EIS capabilities of a Zennium workstation where a higher compliance voltage is necessary, or as a standalone instrument to run DC-only measurements. The XPOT provides up to ±500 mA output current at ±25 V compliance voltage.
 
The XPOT operates either as a standalone device under PC control for DC-only measurements, or in combination with a Zennium electrochemical workstation for both DC measurements and AC impedance measurements.
 
Customers not interested in operating the XPOT as a standalone device can instead connect it to a Zennium workstation. The XPOT is controlled by an EPC42 which is a plug-in module for the Zennium workstations. Each EPC42 can control up to four XPOTs. Up to four EPC42 cards can control up to 16 XPOTs by one Zennium. The XPOT is completely integrated into the Zennium operating environment. Thus, all acquisition and analysis techniques that run on the Zennium can be applied with the XPOT as well.
