NEISYS Electrochemical Impedance Analyzer

New Compact Analyzer for Electrochemical Impedance Spectroscopy

NEISYS is the latest Novocontrol development, a compact high-performance device for electrochemical impedance measurements. It combines modern potentiostatic and galvanostatic functions based on a digital control design with a state-of-the-art electrochemical impedance analysis system in a compact case of very small footprint. In its base version, we offer a versatile measurement device with specifications very well suited for many standard EIS applications at an affordable price.

The standard configuration can be extended by various options (see below) to top-class performance (complete specification) wherever needed. Examples are high-measurement rates and higher frequency options, extended ranges and accuracy, and particular applications like non-linear spectroscopy/higher harmonics analysis. NEISYS comes with an easy-to-use software (running on contemporary Windows systems) with Ethernet as a both inexpensive and reliable system interface.
