Reference 600™

The Reference 600 is a high performance, stand alone, computer-controlled potentiostat/galvanostat/ZRA that interfaces with a computer via USB. The Reference 600 is particularly suitable for applications in physical electrochemistry, sensors, coatings, and corrosion.

Overview

The Reference 600 is a high performance, research grade potentiostat/galvanostat/ZRA. The Reference 600 has 11 current ranges from 600 milliamps to 60 picoamps and a compliance voltage of +/- 22 volts. The Reference 600 has on-board electronics for electrochemical impedance spectroscopy measurements over a frequency range of 1 MHz down to 10 microHz. Attention to detail in component selection and design yields a potentiostat with one of the lowest noise specifications in the industry.

Applications

  • Physical Electrochemistry
  • Sensor Development
  • Corrosion Measurements
  • Coatings Evaluation
  • Microelectrodes
  • Fast Cyclic Voltammetry
  • Electrochemical Noise

Standard Features

  • 2, 3, and 4 electrode measurements
  • 3 Control Modes
    • Potentiostatic, Galvanostatic and Zero Resistance Ammeter.
  • Electrical Isolation
    • Floating instrument: use with autoclaves, mechanical stress apparatus, or pipeline probes.
  • Portable
    • Size of a chemistry textbook, weighing only 3 kgs (6.6 lbs). Easy USB 2.0 connection to a Windows computer.
  • Built-In EIS
    • On-board DDS to perform EIS from 10µHz to 1MHz. See Accuracy Contour Plots below.
  • DSP (Digital Signal Processing) Mode
    • Oversamples for improved signal-to-noise.
  • Current Interrupt and Positive Feedback iR Compensation
    • Gamry potentiostats and their controlling software use control loop algorithms to accurately measure and correct for uncompensated resistance.
  • Auxiliary I/O
    • Control additional equipment via additional I/O interfaces: external signal input, analog voltage output, analog current output, auxiliary A/D input, and digital I/O connector.
  • Multiple Potentiostat Capability
    • Up to eight Reference 600 Potentiostats can be attached and installed on one computer, running at the same time performing separate experiments (requires USB hub).
  • Fast Setup
    • Load the Gamry software, connect the USB cable, and start your experiments.
  • Warranty
    • Protected by 2-year factory service warranty.
