The IviumStat is available in two versions:
|
|
and |
|
Key features:
• Wide application range:
The instrument is well suited for applications requiring a wide dynamic range, such as Battery-testing, Corrosion-measurements and Electrochemical Research applications.
• Complete solution:
The IviumStat offers a complete package. The hardware includes a build-in high-performance Frequency Response Analyser, and all the standard Electrochemical techniques. All measurement and dataprocessing software is included (for Windows based pc’s).
• Safety:
The compliance (maximum current or potential) of the instrument can be defined by the operator. Thus valuable samples may be protected, and unsafe situations prevented.
• Automation:
Multiple analog and digital input & output ports are available, that can monitor & control peripheral equipment. The included software integrates this functionality.
• Multiple Channel option:
Up to 64 IviumStats may be controlled with a single PC via USB.
• Expandibility:
optional Bipotentiostat-, True Linear Scan- and Coulometer-modules are available.
