High flexibility high precision high reliability are thebasic elementswhich make the advanced concept of the IM6
|
| Equipped
with a programmable potentiostat, a pair of high precision amplifiers
for current and potential, a flexible frequency generator/analyzer
and four slots for additional input and output modules the is designed
for nearly all measurement situations in the electrochemistry lab. Specially
designed for spectrum analysis in the electrochemical field, the
modular hardware concept of the IM6
allows
you to configure the IM6 for applications far beyond impedance spectroscopy.
With the appropriate hardware and software modules you can perform nearly
all important data acquisition and analysis techniques which are required
by electrochemical applications.
This is why we call the IM6 an Electrochemical Workstation |

| The Electrochemical Workstation IM6 has been developed with a background of 15 years of know-how in the field of impedance spectroscopy and electrochemical measurement techniques. It is based on the high end data acquisition system AMOS/ANDI and has therefore access to all its hardware and software modules. Very special, partially patented measurement and analysis techniques guarantee highest accuracy and minimal interference with the test object. The great number of different modes of acquisition and analysis as well as the unique upgrade concept make the IM6 an indispensable universal measurement tool in electrochemical laboratory. |
