Reference 3020AE
The Reference 3020AE has the same specifications as the Reference 3020 but with eight auxiliary electrometers: the same ±3 A at ± 11 V applied (±17.5 V compliance), ±36 V at ±1.5 A . The eight additional voltage measurement channels allow you to measure impedance on the individual cells of a stack simultaneously, to 100 kHz. Built for battery, electrolyzer, and fuel cell development.
- Eight auxiliary electrometers for simultaneous additional voltage measurements
- Two switchable compliance settings: ±36 V at ±1.5 A, or ±17.5 V at ±3.0 A
- Eleven current ranges from 300 pA to over 3 A, thirteen with internal gain
- High-voltage electrometer for stack voltages up to ±36 V
- Built-in EIS to 3 MHz — 500 kHz on high compliance
- Separated voltage and current cables for accurate EIS
Published EIS accuracy, not claimed accuracy
Overview
The Reference 3020AE is a high-current, high-performance USB potentiostat with 11 current ranges from over 3 amps to 300 picoamps and compliance voltage up to 36 volts. With on-board electronics for electrochemical impedance spectroscopy, the Reference 3020 can make measurements over a frequency range from 10 μHz to 3 MHz. On the Reference 3020AE the auxiliary electrometer is fitted as standard, adding eight differential voltage inputs for measuring impedance on the individual cells of a stack simultaneously. It was developed to be especially useful in applications for Energy Storage and Conversion (ESC) devices.
Auxiliary Electrometer
On the Reference 3020AE the auxiliary electrometer is factory-installed as standard. It adds an array of eight differential voltage inputs; each of the eight channels can measure a ± 5 volt signal anywhere over the instrument’s entire compliance voltage range. Impedance measurements up to 100 kHz can also be performed using the auxiliary electrometer, which is what allows impedance to be measured on the individual cells of a stack simultaneously rather than one cell at a time.

Auxiliary Electrometer Cables: The standard Auxiliary Electrometer cables are 90 cm. Extended length cables (1.5 and 3 meter) are available.
The Reference 3020AE™ is a high-performance Potentiostat/Galvanostat/ZRA with a maximum current of ±3.0 A (at ±17.5 V compliance) and a maximum voltage of ±36 V (at ±1.5 A), supplied with the auxiliary electrometer factory-installed. Its eight differential voltage inputs allow impedance to be measured on the individual cells of a stack simultaneously. The Reference 3020AE is recommended for battery, electrolyzer, or fuel cell development, as well as general electrochemical measurements.
Accuracy Contour Plot
Electrochemical Impedance Spectroscopy
Gamry provides Accuracy Contour Plots for every one of our potentisotats that is EIS-capable. The accuracy contour plot provides a detailed look at the performance you can expect from your instrument in real-world situations. The results include the cell cable. Accuracy contour plots are important because they let you compare the performance of different manufacturers to ensure you are getting the best possible measurement.
