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.

• Tests begin with a built‐in safety check of all control values.

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 offers an EIS Interface for approved 3rd party EIS modules for customers who wish to perform electrochemcial impedance spectroscopy experiments.  The EIS Interface allows a single EIS module to be shared across up to 32 channels; fully maximizing the duty cycle of EIS station and Arbin tester.  No change in connection is necessary. Frequency range of 10uHz to 2MHz.
	Arbin offers Auxiliary Voltage Inputs that can be used as additional reference electrodes in a multi-electrode experiment.  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.
	Temperature Measurement Inputs are offered for Type-T or K Thermocouple, or 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 MZTC Battery Test Chamber Arbin’s Cell-Isolating Thermal Safety Chamber (MZTC) is a battery test chamber with 8 independent temperature chambers in 1.  Insulation and protection between each chamber provides greater temperature control and a safe testing environment by isolating each cell or set of cells, as well as making connections easy.

	Arbin EV Battery Pack Tester with Chamber This module allow’s the Arbin tester to interface with approved 3rd party temperature/environmental chambers from other manufacturers.  The Arbin software can turn the chamber on/off and adjust temperature during testing.  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 are offered to interact with external hardware devices. — 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 any device that operates in a 0(2)-10V signal such as pumps, valves, etc.
	Arbin’s Auto-Calibration module allows channels to be calibrated automatically with connected to an appropriate source meter.  While the calibration interface is built into the software for all systems, this module removes the need for human involvement in the process and is recommended for systems with channel quantities greater than 32.
	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.
