|
• Low noise and galvanic isolation: The instrument is electrically isolated from power lines and PC. It has a superior noise immunity, and is capable of determining very small signals, such as is required in nano-technology applications. Also, the instrument may be applied in situations where the sample must be disconnected from a common ground (floating). • Complete solution: The CompactStat 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. |

Power Booster:The power of the CompactStat can be greatly increased by adding the Plus-module. The Plus-module connects in front of the CompactStat in-line with the cell cable. However, the power required and delivered by the Plus-module cannot be sustained from the USB anymore. Therefor a mains-adapter is needed. The Plus-module is available in two configurations, increasing the power specifications of the CompactStatPlus to: |
