The Gamry Reference 3000AE is the Reference 3000 potentiostat, galvanostat and zero resistance ammeter (ZRA) with the Auxiliary Electrometer added. Every Reference 3000 specification applies, and the Auxiliary Electrometer section is listed alongside it below.
Gamry describes what the Auxiliary Electrometer adds as eight additional voltage measurements, ideal for stack testing. In practice that means the individual cells of a stack can be monitored while the main channel drives the stack as a whole.
Gamry's own note on the specification sheet is worth repeating: Gamry potentiostats are specified conservatively, and actual performance may be significantly better than the published specifications indicate. Values listed as typical are representative rather than guaranteed.
Gamry Reference 3000AE Auxiliary Electrometer
The Gamry Reference 3000 potentiostat, galvanostat and ZRA supplied with the Auxiliary Electrometer, which adds eight additional voltage measurements for stack testing. All Reference 3000 specifications apply, with the Auxiliary Electrometer figures listed separately.
