NEISYS

Novocontrol
Electrochemical Impedance
Measurement System

NOVOCONTROLNew Compact Analyzer forElectrochemical ImpedanceSpectroscopy
NEISYS is the latest Novocontrol development, acompact high-performance device for electroche‐
mical impedance measurements. It combines mo‐dern potentiostatic and galvanostatic functions
based on a digital control design with a state-ofthe-art electrochemical impedance analysis system
in a compact case of very small footprint. In its ba‐
se version, we offer a versatile measurement device
with specifications very well suited for many stan‐
dard EIS applications at an affordable price.
The standard configuration can be extended by va‐
rious options (see below) to top-class performance(complete specification) wherever needed. Examp‐
les are high-measurement rates and higher frequen‐cy options, extended ranges and accuracy, andparticular applications like non-linear spectroscopy/
higher harmonics analysis. NEISYS comes with aneasy-to-use software (running on contemporaryWindows systems) with Ethernet as a both inex‐
pensive and reliable system interface.
Performance
Using state-of-the-art digital processing techniques,
NOVOCONTROL Technologies delivers formerly
inaccessible performance, such as high input impe‐
dance, wide impedance range, and high phase an‐
gle resolution. These features create newopportunities for impedance spectroscopy applica‐
tions. By separating the signal current and voltage
sensing paths, the four-terminal configuration of
the NEISYS analyzer, in particular, reduces the ef‐
fects of lead inductance and stray capacitancewhich are particularly important in electrochemical
applications.
At an affordable price, NEISYS delivers the per‐formance required to run all kinds of electrochemi‐
cal impedance measurements.
DETACHEM Software Support Included
DETACHEM, our new con‐trol and evaluation software,is included. It supports mea‐
surements in both frequency
and time domains and al‐lows a smooth start by offe‐
ring various standard experiments which are set-up
within minutes.
