multi channel potentiostat galvanostat

MSTAT (Multi-Channel Potentiostat / Galvanostat)

Product Highlights

Channel Voltage  -5~5V
Channel Current 0.001~5A
Channel Number 4~64

Arbin's 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.

Arbin Instruments’ MSTAT offers a multitude of features that support advanced cell testing and electrochemical research. Each channel of the MSTAT provides four current ranges with industry-leading 24-bit resolution. MSTAT channels also have an additional reference electrode built in.

Channels are fully parallelable, so any number of channels can. be connected to increase the current handling capacity. Multiplexed EIS (up to 2MHz) allows a single module to be customized to share between 4 and 32 channels.

In addition to these features, the MSTAT offers dynamic data acquisition based on factors including time, voltage, and current. This allows users to capture more data when you need it while maintaining more efficient file sizes. Comprehensive safety features help to keep the system and testing environment safe.

Importance of Precision

This plot illustrates the difference between an Arbin battery tester and another leading manufacturer. The first of the two distinct dips in the plot may have been missed using inferior test equipment. While many companies try to sell the same legacy 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 LBT, RBT-Cell, and HPS test equipment series. The HPS ultra-high precision systems represent our premium product, but LBT is superior to other standard testers on the market.

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 at right.

What Affects Test Equipment Precision

Resolution of ADC
Non-linearity of calibration
Short-term drift (temperature)
Long-term drift (material characteristics)

Arbin Test Equipment Improvements
Higher Resolution
Improved Software Algorithms

New Method of Time Keeping
New Materials


Auxiliaries and Optional Accessories Available to Enhance Testing

MZTC Multi-Chamber

Arbin Battery Test Chamber

Arbin's MZTC "Multi-Chamber" provides 8 fully independent mini-temperature chambers to isolate cells under test.

EIS Integration

Add a Gamry EIS unit or Arbin ACIM module that is shared across up to 32 test channels (each).

Temperature Control
Temperature Measurement

EIS (electrochemical impedance spectroscopy) is an optional module to add to Arbin test systems to further enhance their capability.  Each EIS module can be shared/used by up to 32 Arbin test channels.  EIS data is synchronized with Arbin test data.
Compatible EIS modules include:
- Gamry 1010E
- Gamry 5000E
- Gamry Ref 3000
- Arbin ACIM module

Auxiliary Voltage Measurement
Digital or Analog I/O

Arbin offers an optional AutoCal module which can be used to re-calibrate the system when needed.  All Arbin test equipment include a calibration interface as standard that can use an external meter to check or perform re-calibration.  The AutoCal module is used to automate this process and will function without the need for an external meter.
NOTE: Arbin recommends equipment calibration is checked annually and re-calibrated as-needed.

AutoCal modules are available rated up to 200A, and High precision shunts are also available to use up to 600A.
