Make impedance measurements on up to 8 batteries sequentially

The EIS Box is a multiplexed eight channel instrument designed for impedance measurements on batteries and is typically used in conjunction with a battery cycler. It is capable of EIS from 100 kHz down to 10 µHz.  


The EIS Box comes with 8 x 3 m cell cables and is designed to be used in conjunction with a battery tester/cycler to provide impedance testing. Cycle testing of the battery would be provided by the battery tester/cycler. It can be installed in a 19-inch rack (similar to the ECM8 multiplexer). Connection to the EIS Box is made through LAN ethernet using an internal microprocessor that can translate USB to Ethernet commands. As with a USB connection to our potentiostats, the EIS Box has to be in constant contact with the host computer for experiments to be performed successfully. Connection via ethernet needs to be accomplished over a local network only; connection over the internet will not be possible.  Only EIS experiments up to 100 kHz are available.
