OctoStat

High performance rack-mountable battery test system with integrated impedance analyser

 
The OctoStat is a multi-channel test system with a fixed number of 8 channels per unit, including low current measurement possibility down to 100pA full-scale with fA resolution. Each channel is equipped with its own dedicated FRA/EIS and an input for temperature measurement. The OctoStat is built into a 19inch rack mountable housing.


The OctoStat is designed for applications where multiple cells are operated in parallel for long periods of time. It also includes an integrated DataSecure that stores all data independent of the PC to ensure that in the event of communication loss or computer crash, the measurement will continue and measurement data is never lost. This system stability makes the OctoStat a perfect system for long term testing applications, such as battery/fuel cell testing, electrode development, biotechnology, and corrosion.

IviumSoft: all you need in a single suite


Ivium provides outstanding software to match every research application. IviumSoft intuitive software suite is feature-rich and is common to all of our instruments. 

It comprises several operation modes which offers one complete powerful and versatile package of control and analysis software. The IviumSoft control software allows control of separate channels or all channels simultaneously with synchronized start. Data can be plotted per channel or simultaneously for all channels on a single screen. IviumSoft can also interface with and be controlled from LabVIEWTM, C++, Delphi, etc. 

A full suite of IviumSoft is included with each instrument as standard.

OCTOBOOST for additional power needs (up to 128A)


The OctoBoost16000 offers a flexible high current solution for both the OctoStats family. In combination with an OctoStat, the 16A channels on the booster can be combined (as long as the channels are neighbouring) to give a variable max current up to 128A (e.g. 8 x ±16A, 4 x ±32A, 2 x ±64A, 1 x ±64A and 4 x ±16A, 1 x 128A, etc.).
