Reference 3000 With Auxiliary Electrometer

The Reference 3000AE™ with Auxiliary Electrometer,  is a high-performance Potentiostat/Galvanostat/ZRA just like the Reference 3000 but the Reference 3000 AE features eight additional electrometers and is the ideal potentiostat for battery, capacitor, and fuel cell development. Key features include:
  • Eight additional voltage measurements – Ideal for stack testing
  • Maximum Applied Potential - Up to +/-32V@+/-1.5A or +/-15V@+/-3A
  • EIS - 10 μHz - 1 MHz

Product Category: Potentiostats

Industry: Electrochemistry

Supplier: Gamry



The Reference 3000 AE is a high-current, high-performance potentiostat designed for use by battery, fuel cell and supercap researchers.  The additional voltage sensing channels make it especially useful for testing of multiple cells within a stack or measuring auxiliary voltages from devices such as pressure gauges or pH meters.

Auxiliary Electrometer Cables: The standard Auxiliary Electrometer cables are 90 cm. Extended length cables (1.5 and 3 meter) are available.


Below are additional details regarding the capabilities of the Reference 3000 AE potentiostat. Each bullet point contains a list of the type of techniques available for the instrument to run.

  • Physical Electrochemistry  - Techniques such as cyclic voltammetry, chronoamperometry, and chronopotentiometry and derivatives of these techniques.
  • Pulse Voltammetry - Techniques such as pulse voltammetry, square wave voltammetry, and associated stripping techniques such as anodic stripping voltammetry.
  • DC Corrosion - Run standard DC corrosion tests such as polarization resistance, potentiodynamic, cyclic polarization, and galvanic corrosion in addition to a number of others.
  • Electrochemical Energy - Test single-cells and stacks of various batteries, fuel cells or supercapacitors. Includes charge, discharge, cyclic charge-discharge techniques, potentiostatic, galvanostatic, self-discharge, leakage rate, and read cell voltage.
  • Electrochemical Signal Analyzer -  Designed specifically for the acquisition and analysis of time-dependent electrochemical noise signals. Cell voltage and current are continuously monitored at rates from 0.1 Hz to 1 kHz. A full featured set of analysis tools provides powerful analysis features such as statistical analysis, detrending, impedance spectra, and histogram analysis.
  • Electrochemical Frequency Modulation - A non-destructive corrosion rate measurement technique. It allows for measurement of the corrosion rate without prior knowledge of the Tafel constants. In addition, the technique determines the Tafel constants and provides 2 internal validity checks.
  • Critical Pitting Temperature - controls a Gamry Potentiostat, TDC4 Temperature Controller, and associated accessories to automatically measure the Critical Pitting Temperature of a material.
  • Electrochemical Noise - A more general form of electrochemical noise testing. It is also an ECM8 Multiplexer compatible electrochemical noise software package.
  • Electrochemical Impedance Spectroscopy - includes experimental scripts for potentiostatic, galvanostatic and hybrid impedance spectroscopy experiments in addition to single frequency techniques like Mott-Schottky. We also have our unique power-leveling multisine technique that improves signal-to-noise across the spectrum. On the analysis side, it provides tools for fitting spectra to equivalent circuit models, Kramers-Kronig transform for data validation and a graphical model editor. Our software even includes a script for EIS simulation.
  • eChemDC Toolkit - contains all of the capabilities of the eChemBasic and further extends these capabilities by adding advanced signals and data acquisition modes to simplify implementing experiments like cyclic voltammetry, pulse voltammetry, and dynamic DC corrosion techniques. Also includes more advanced stop tests, particularly useful in fast experiments.
  • eChemAC - Includes full capabilities of eChemDC Toolkit plus allows electrochemical impedance spectroscopy (EIS) and EFM experiments.
