Reference 3000™

Overview

The Reference 3000 is the latest addition to the Reference family of potentiostats. The Reference 3000 is a high current, high performance stand alone potentiostat with 11 current ranges from 3 amps to 300 picoamps and compliance voltage up to 32 volts. With on-board electronics for electrochemical impedance spectroscopy, the Reference 3000 can make measurements over a frequency range from 10 μHz to 1 MHz. The Reference 3000 also has an optional unique feature enabling the measurement of 8 additional voltages. It was developed to be especially useful in applications for Energy Storage and Conversion (ESC) measurements.

Options

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.
