Reference 30k Booster

The Reference 30k™ Booster is ideal for higher current applications such as large format batteries and lead-acid batteries.  It´s also ideal for fuel cell testing.  Ground isolation allows for operation in parallel with a power supply or electronic load or grounded cells.  The Reference 30K Booster attaches to a Reference 3000 Potentiostat or Reference 3000 Auxiliary Electrometer to bring the current limit up to ± 30 Amps with compliance limits of +20 and -2.5 V.  This high current device features impressive bandwidth allowing EIS measurements up to 300 kHz.

System Highlights


The Reference 30k Booster for the Reference 3000 Potentiostat is an external hardware option which increases the current limit of the Reference 3000/3000AE to ± 30 Amps.  It features a class-leading bandwidth of 300 kHz, allowing for high-frequency EIS measurements and rapid pulsing experiments.  The Reference 3000 Potentiostat plus the Reference 30k Booster is an ideal system for the evaluation of new technologies for batteries, fuel cells, and next generation supercapacitors.  The compliance limits of the Reference 30k allow complete discharge (through zero volts) and can accurately measure impedance values below 100 μΩ. 

The Reference 30k is not only limited to high current applications but has been uniquely designed to allow pass-through measurements. This means that you can use the 3 A, 300 mA, and 30 mA ranges of the Reference 3000/3000AE while still connected to the booster. Our systems are designed to pick the most appropriate range, giving you the highest resolution possible. 

Electrochemical Impedance Spectroscopy

The Reference 30K Booster is fully capable of performing electrochemical impedance spectroscopy.  The shorted lead curve shown below is a measure of the limits of the instrument.  

Rapid Pulsing

The booster's impressive 300 kHz bandwidth also allows it to do rapid pulsing experiments for techniques for cell characterization.  As mentioned above, the system's response (including electrochemical cell) is dependent upon the instrument's internal resistances as well as the resistance of your cell.  Below is an example of a 200 μs 12 A pulse on a 200 mΩ cell.
