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 up to 2MHZ and is multiplexed internally. This means you never have to change connections when performing EIS on the tester.

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.
|Arbin’s EIS Integration solutions are designed to support full or half-cell battery characterization or any other electrochemical device. Arbin’s EIS board can be easily integrated with your cycler for lower frequency needs. Arbin also has an integrated EIS solution that combines the multi-channel, high-precision battery test performance of Arbin with advanced EIS capability for higher frequency. These solutions share up to 32 Arbin channels (through multiplexing) with a single EIS unit to maximize the duty cycle of both instruments. No change in connection is necessary.
Frequency range of 10μHz to 100kHz integrated with Arbin cycler.
|Auxiliary Voltage Inputs can be added to any Arbin system to provide additional reference electrodes in a multi-electrode experiment or to monitor cell voltages within a pack. Data logged from auxiliary voltage inputs can be flexibly assigned by the user to one, many, or all of the main charge/discharge channels. Measurements can be used to control the test, act as safety limits, or simply record data.|
|Auxiliary Temperature Inputs are offered for Type-T or Type-K Thermocouple as well as 10kohm or PT100 Thermistor sensors. Temperature data logged from these inputs can be flexibly assigned by the user to one, many, or all of the main charge/discharge channels. Temperature can be used to control the test, act as safety limits, or simply record temperature measurements.|
Arbin’s Multi-Zone Temperature Chamber (MZTC) features 8 fully independent mini-chambers with a temperature range of [ambient-10] to 60°C. Each mini-chamber can hold 1 to 4 cells, depending on cell type and amperage. Insulation and protection between each chamber provide greater temperature control and a safe testing environment by isolating each cell or set of cells, as well as making connections easy. Racks are available for multiple MZTC units.
The Temperature Chamber Interface (MTCI) allows the Arbin system to communicate with an approved third-party temperature/environment chamber. Arbin’s software can turn the chamber on/off and adjust the temperature during the test. Temperature setpoints from the chamber controller are automatically logged in the data and independent temperature measurements are available using thermocouple or thermistor inputs.
|Digital and Analog Input/Output channels allow the Arbin system to interact with external hardware and devices through a digital on/off relay signal, or an analog 0-10V signal.
— The Digital I/O will send and receive a simple on/off, high/low relay signal. It can activate a BMS, receive a confirmation signal, and many other options.
— The Analog I/O will control devices such as pumps, valves, etc.
|The Auto-Calibration module automates the calibration process, enabling the Arbin system to self-calibrate when connected to an appropriate source meter. A software interface for manual calibration is a standard feature for all Arbin testers, but Auto-Calibration is recommended for systems with more than 32 test channels.|
|The Uninterrupted Power Supply (UPS) option will provide backup power to the PC with your Arbin system. It allows the test to automatically pause and wait for power to be restored to the tester and will automatically and safely resume testing after brief outages. Otherwise, the software and PC will safely be shut down.|
|A variety of Battery Holders and Racks are available for coincells, cylindrical cells, pouch/flat cells, and more. These individual holders are available for currents up to 300A. The wheeled battery racks make it easy to organize large quantities of cells with removable trays and cable organization.|
|The Redundant Safety Monitoring System (RSMS) can be placed in series with any battery tester including those from USA, Europe, and Asia. The RSMS allows users to set a limit for Voltage, Current, Power, and Temperature that will automatically disconnect the battery or device under test is a safety limit is reached. Many manufacture’s claim to have comprehensive safety features, but the RSMS guarantees and extra layer of protection to help prevent failure events.|

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 30 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.
