Zennium X
The Zennium X is the most highly capable electrochemistry workstation carried by Admiral Instruments. It is comprised of a potentiostat / galvanostat and a frequency response analyzer (FRA) unit with a frequency range up to 12 MHz at ±4 A and at a compliance voltage of up to ±32 V. With a standard input impedance of more than 10 TΩ || 5 pF, this workstation is suitable for a wide range of electrochemical measurements, even moreso than the Zennium Pro.
Key Highlights:
-
32-bit converter for exceptional DC accuracy
-
EIS frequency range: 10 µHz to 12 MHz
-
HDP technology with 24-bit AC resolution for high dynamic accuracy
-
Integrated ADF technology enabling ultra-fast CV up to 10 kV/s
