Reference 600™

The Reference 600 has been replaced with the Reference 600+

System Highlights


The Reference 600 is a high-performance, research-grade potentiostat/galvanostat/ZRA designed for fast, low-current measurements.  It does well for a variety of applications such as physical electrochemistry (especially at microelectrodes), fast cyclic voltammetry, electrochemical corrosion, electrochemical noise measurements, paints and coatings, and sensors.  

It has a number of auxiliary input and outputs designed to help you interface or control ancillary equipment such as a rotating disc electrode. It also has a thermocouple for temperature measurements. 

Electrochemical Impedance Spectroscopy

The Reference 600 comes fully equipped to perform electrochemical impedance spectroscopy.  The Accuracy Contour Plot shown below provides a detailed look at the performance you can expect from your instrument in real-world situations. The results include the cell cable.

  • Extended Cable Lengths
    • Extended length cell cables (1.5 m, 3 m, 10 m) are also available for your convenience.

More details

Below are additional details regarding the capabilities of the Reference 600 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.
  • eChemAC - Includes full capabilities of eChemDC Toolkit plus allows electrochemical impedance spectroscopy (EIS) and EFM experiments.
