The Gamry Reference 620 is a potentiostat, galvanostat and zero resistance ammeter (ZRA) for the electrochemistry laboratory. Gamry's brochure describes it as "designed to bring you maximum performance for demanding applications", and lists its headline features as fast CV, EIS to 5 MHz, ultra low current, floating operation and low noise.
Gamry states the instrument is suited to corrosion measurement, paints and coatings, bioelectrochemistry and sensor development, physical and analytical electrochemistry, and energy devices. It supports 2, 3, 4, 5 or 6 cell connections and is isolated from earth. Gamry quotes an intrinsic noise level of <2 µV rms, and both current interrupt and positive feedback modes of iR compensation.
The footprint is small for the performance: Gamry gives it as only 9x19x27 (WxHxD) cm and 3 kg, so it sits on a crowded bench without taking a whole shelf.
Values listed as typical are representative rather than guaranteed.
