Standard Features

2, 3, and 4 Electrode Measurements
High Voltage Electrometer Mode for Measuring and Applying Potentials Up to 32V
3 Control Modes
Potentiostatic, Galvanostatic and Zero Resistance Ammeter.
Electrical Isolation
Floating instrument: use with operating fuel cells, batteries and autoclaves.
Separated Voltage and Current Cables
Always accurate EIS measurements.
Size of two chemistry textbooks, weighing about 5 kgs (11 lbs). Easy USB 2.0 connection to a Windows computer.
Built-In EIS
On-board DDS to perform EIS from 10µHz to 1MHz. Simply purchase a software license and begin acquiring accurate EIS data. See Accuracy Contour Plot below.
DSP (Digital Signal Processing) Mode
Oversamples for improved signal-to-noise and to ensure accurate capacitance measurements.
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.
Multichannel Capability
Up to eight Reference 3000 Potentiostats can be attached and installed on one computer (requires USB hub).
High Voltage Electrometer
A special high voltage electrometer allows measurement and potentiostatic control of voltages up to ± 32 volts.
Fast Setup
Load the Gamry software, connect the USB cable, and start your experiments.
Protected by 2-year factory service warranty.
Accuracy Contour Plot
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.



Auxiliary Electrometer
The auxiliary electrometer is a factory installed option that adds an array of eight differential voltage inputs. Each of the eight channels can measure a ± 5 volt signal anywhere over the Reference 3000’s entire compliance voltage range. Impedance measurements up to 100 kHz can also be performed using the auxiliary electrometer.
Extended Cable Lengths
Extended length cell cables (1.5 and 3 meter) are also available for your convenience.
Auxiliary Electrometer Cables: The standard Auxiliary Electrometer cables are 90 cm. Extended length cables (1.5 and 3 meter) are available.
