Arbin’s Multi-Channel Potentiostat/Galvanostat (MSTAT) system is designed for high performance electrochemical research of battery materials and advanced battery cell testing. Each channel is an independent potentiostat/galvanostat and gives users full control of test profiles and data logging to offer unmatched flexibility. No other potentiostat manufacturer offers range of channels, voltage, current, and feature-set as Arbin. Researchers and startup companies who begin working with Arbin can continue to use our battery testing systems and software solutions as they grow and expand.
The Arbin MSTAT provides true bipolar circuitry to ensure cross-zero linearity with no switching time between charge and discharge. MSTAT hardware provides both digital and analog voltage control. Digital control maximizes the safety of battery cycling and can handle dynamic device resistance, while analog control enables the fast response and stability necessary for electrochemical applications.
This product consists of independent potentiostat/galvanostat channels for testing battery materials and other electrochemical applications, and is intended to provide an economical solution for applications requiring high‐precision measurements and fast data sampling. All Arbin testing systems come with a PC pre-loaded with our MITS Pro and Data Watcher software for creating test profiles, real‐time data monitoring, and data plotting & analysis.
Electrochemical Impedance Spectroscopy (EIS) is optionally available on all channels and is multiplexed internally. This means you never have to change connections when performing EIS on the tester.

Options/Auxiliaries
Arbin Instruments provides a wide variety of auxiliary modules for expanding the capability of the main charge/discharge control circuitry. Modules can either be placed in the main chassis, or in a small external chassis. This also makes it easy to add auxiliary options to existing systems.
EIS – Interface for an approved 3rd party EIS module to allow EIS measurements without changing connections.
Auxiliary Voltage – Used as additional reference electrodes to measure voltage.
Temperature Thermocouple/Thermistor – Used to record temperature as well as control the test schedule
TCI (Chamber Interface) – Interface with a 3rd party temperature chamber so Arbin software can turn chamber on/off and adjust temperature
MTC (Arbin Multi-Chamber Temperature Chamber) – Arbin offers 
a compact temperature chamber for battery testing designed to operate between 10 and 60C. [LEARN MORE]
Digital I/O – Send and receive a simple on/off signal to interact with external devices.
Analog I/O – Control any device operating on a 0(2)‐10V signal.

Importance of Precision
This plot illustrates the difference between an Arbin battery tester and another leading manufacturer. The two distinct dips in the plot may have been missed using inferior test equipment. While many companies try to sell the same antiquated equipment for over a decade, Arbin has been hard at work improving our designs to meet future industry demands. We learned a lot during our three year ARPA-E project to develop high-current high-precision testers, and have implemented this new technology in our MSTAT, LBT and HPT test equipment series. The HPT and MSTAT systems represent our premium product, but LBT is superior to other standard testers on the market.

What Affects Tester Precision |
Arbin Tester Improvements |
Measurement precision is more critical for long‐term battery testing and long‐term battery projections than control accuracy alone. Most other battery testing systems do not correctly specify their precision and/or have relatively poor precision, which hinder the conclusions drawn from results data. Important trends and electrochemical indicators may remain unnoticed; lost in the measurement noise as illustrated above.
Our hope is that these higher degrees of measurement precision will lead to new discoveries and characterization metrics across the energy storage industry for all organizations, not only those looking at coulombic efficiency as a key indicator.
How to Evaluate Battery Test Equipment
Batteries are a critical component of many products, and energy storage plays a very active role in our lives even outside of the research/industry setting. Therefore, selecting the right battery test equipment is an important decision for companies and the individual researchers who are responsible for producing results, whether they are starting small, or at massive scale.
The expert engineers at Arbin have been advancing the benchmark of “state-of-the-art” battery test equipment for over 27 years. We are defined by innovation, from being the first to apply multiple current ranges on a single test channel to more recently being the only company to offer true high-precision testing for high current applications, and supporting “Turbo Mode” with smart battery modules. We continue to learn from our industry partners and work with them on key technology breakthroughs.
