OctoStat
High Performance Multi-Channel Test System
The OctoStat is as a sophisticated multi-channel test system, offering a fixed configuration of 8 channels per unit, designed to cater to applications requiring the parallel operation of multiple cells over extended periods. Its combination of multi-channel capabilities, advanced impedance analysis, and secure data storage ensures comprehensive and accurate results in a wide range of research areas.
Key Specifications of the OctoStat
High Performance & High Stability
Affordable high-spec and high stability electrochemical test system ideal for applications such as long-term battery/fuel cell testing, electrode development, biotechnology, and corrosion studies.
20M points/channel
The integrated DataSecure feature ensures that all data is stored independently (with up to 20 million points per channel), safeguarding against communication loss or computer crashes and ensuring that measurement data is never lost.
19-Inch Rack-Mountable Housing
The OctoStat’s robust build is housed in a 19-inch rack-mountable casing, making it suitable for high-density setups, with up to 128 channels per rack, making it suitable for large-scale long time testing setups.
USB / Lan connectivity
The uDataSecure module supports multiple PC connections via LAN (Ethernet), enhancing data accessibility and system integration.
Dedicated Embedded FRA/EIS
Unique to each channel is a dedicated Frequency Response Analyzer/Electrochemical Impedance Spectroscopy (FRA/EIS) in each independent channel, not multiplexed. Capable of EIS during DC charge/discharge.

Additional Power Requirements?
The OctoBoost16000 presents a flexible, high-current solution compatible with the OctoStat family. When combined with an OctoStat device, the 16A channels on the booster can be grouped to provide a variable maximum current up to 128A.
This could be in various configurations, such as
- 8 x ±16A,
- 4 x ±32A, or 3 x ±32A + 1 x±16A, or...
- 2 x ±64A, or 1 x ±64A and 4 x ±16A, or 1 x ±64A and 2 x ±32A, or...
- 1 x 128A
This flexibility makes OctoBoost an essential addition for high-current battery testing applications.
