Potentiostats
Reference 3000 & 30k Booster
Rapid, High-Current Pulsing & Superior, Low-Impedance EIS
For those interested in determining the characteristics of batteries, especially by discharging them to see their changes in impedance, Gamry Instruments offers the Reference™ 3000 potentiostat plus our 30k Booster. This combination of instruments is useful for running stress tests on batteries, by applying rapid, high-current pulses singly or repeatedly.

Gamry’s Reference 3000 and Reference 30k Booster can accurately and reliably generate current pulses as short as the high tens of microseconds.
Reference 30K Booster
Nobody is faster
Distortion-free, rapid pulsing for charge and discharge
30 A Pulse on a 5 mOhm cell
Nobody goes lower
Up to 30A @ 20V, EIS to 300 kHz
200 nOhm Shorted Lead Curve, 20 A rms, 0.9 m cell cable
