Product Details
Overview
The Reference 3020 is a high-current, high-performance USB potentiostat with 11 current ranges from over 3 amps to 300 picoamps and compliance voltage up to 36 volts. With on-board electronics for electrochemical impedance spectroscopy, the Reference 3020 can make measurements over a frequency range from 10 μHz to 3 MHz. The Reference 3020 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) devices.

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 3020’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.
