The Reference 600TM
Potentiostat is the first of our USB-based Potentiostats. The Reference 600 is a high performance Potentiostat.
What does that mean? With the Reference 600, you can measure the impedance
at 1 MHz with less than 2% error! That's because the Reference 600
has a Rise Time of less than 250 nanoseconds! You can acquire data
in DC experiments at 300 kHz, or one data point every 3.3 microseconds! That
translates to a scan rate in cyclic voltammetry of 1200 volts/second with
a Step Height of 4 mV.
The Reference 600 has 11 current ranges from 600 mA to 60 pA. That's
11 different current ranges in the I/E Converter. By increasing the
gain, the instrument can extend to 600 fA full-scale. The Reference
600 is a great Potentiostat for corrosion, physical electrochemistry,
paints and coatings, and the development of lithium ion batteries.
The Reference 600 employs a very clever scheme to reduce the noise levels
in the measurement of the current, voltage, and auxiliary input signal. In addition to a well-designed layout,
components
selected to balance speed and noise, and extensive analog filtering, the
Reference 600 oversamples the voltage and current signals, then averages
to smooth the signal. The Reference 600 samples at 60 kHz (16.6
microseconds/point), then averages this data to provide the measurement at
the Sampling Period you specify during the experimental setup.
The USB Interface allows easy connection to desktop, portable, and laptop
computers. Using a USB hub, you can connect up to eight
Reference 600's to one computer and run them at the same time while doing
completely different experiments.
The Reference 600 has an applied potential range of ±8 volts and a
compliance voltage of ±20 volts.
The Reference is fully isolated
from the computer's chassis ground, so it can work with earth grounded cells. It
offers both current interrupt and positive feedback IR compensation.
16-bit D/A and A/D converters, along with
four terminal current and voltage measurements, provide accurate results down to
1 µV
resolution. The four terminal capability is useful for
electrochemical measurements on membranes or films.
In addition to potentiostatic and galvanostatic modes, the Reference 600
is also designed for Zero Resistance Ammeter functionality. A ZRA is
required for galvanic corrosion measurements and is preferred for
electrochemical noise measurements.
Despite these impressive specifications, the Reference 600 is surprisingly
compact. It measures 10 cm W x 20 cm H x 30 cm D and weighs about 3
kilograms. That makes it easy to carry to your measurement site,
connect to a notebook computer, and make the measurement. Put it in
your briefcase and take it on the plane with you. Place it inside
your glove box!
The Reference 600 has been tested and approved for CE Certification and
meets RoHS requirements.

- Built-In EIS - On-board
DDS to perform EIS from 10µHz to 1 MHz. And not just EIS at 1
MHz, but EIS at 1 MHz with less than 2% error in magnitude and
phase!
- Electrical Isolation - All Gamry potentiostats are fully isolated
(electrically) from the host computer's chassis ground, allowing it to function properly
with earth grounded cells. Use the Reference 600 with autoclaves, mechanical stress apparatus,
or pipeline probes for accurate results.
- Size Does Matter! - Despite
what our competitors think, the performance of a potentiostat is not
proportional to the volume or weight of the potentiostat! Gamry's modern electronic design and extensive use of
surface mount technology packs tremendous capability onto a small area.
Don't be fooled by the small size of the Reference 600; there
are over 2300 parts in each Reference 600! You'll
appreciate the small size because it doesn't consume much of
your bench space. And it weighs about 3 kg so it's easy to
move.
- Current Interrupt and
Positive Feedback iR Compensation - no need to rig your cells with supporting electrolyte
or geometric modifications anymore, Gamry potentiostats and their controlling software use
control loop algorithms to accurately measure and correct for uncompensated resistance.
- Portability - The
Reference 600 easily interfaces to a laptop computer through the
USB Interface. With a weight of 3 kg and a volume of
6000 cm3, it's also easy to carry.
- Auxiliary I/O - The
Reference 600 allows you
to control additional equipment via additional I/O interfaces on
the back panel.
