Overview

The Series G Potentiostat/Galvanostat/ZRA is a high-precision, research-grade electrochemical instrument that is designed to be installed inside a desktop computer. The ultra-compact design is the result of the electronic advances of the last 15 years, such as surface mount technology. It is available in a 300mA and 750mA version to work in many applications. On-board electronics allow EIS scans from 10 µHz to 300 kHz without the need for an external FRA or lock-in amplifier. Extensive voltage and current channel filtering allows quiet measurements in very noisy environments. 16-bit D/A and A/D converters, along with four terminal current and voltage measurements, provide accurate results down to 1 µV resolution.

Applications

• Corrosion Measurement
• Physical Electrochemistry
• Electrochemical Noise
• Sensor Development

Standard Features

• Isolation
  • Floating Instrument - use the Series G with autoclaves, mechanical stress apparatus, or pipeline probes.
• Built-In EIS
  • On-board DDS to perform EIS from 10µHz to 300kHz. See Accuracy Contour Plots below.
• 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 miscellaneous I/O connector.
• Multiple Potentiostat Capability
  • Up to eight Series G 300/750 Potentiostats can be installed in one computer (requires industrial computer).

Warranty

Protected by 2-year factory service warranty.
