Extensions

Photoelectrochemistry / Photovoltaics

Upgrade your ZENNIUM PRO potentiostat to CIMPS system (ZENNIUM PRO + PP212 + accessories) for characterizing your photoelectrochemical, photocatalytical or photovoltaic systems.

CIMPS
The CIMPS system is a powerful tool for the investigation of photoelectrochemical / photovoltaic systems. The system can carry out standard electrochemical techniques and special photoelectrochemical techniques like IMPS/IMVS, CLV and etc. A robust feedback loop ensures constant and reproducible intensity of light illumination during the photoelectrochemical measurements.

CIMPS-QE/IPCE
CIMPS-QE/IPCE is an extended CIMPS system with the capability to measure quantum efficiency (QE) or incident photon to current efficiency (IPCE). During IPCE measurements, a special indicator is also provided which indicates if the measurement parameters are optimal for the IPCE measurement or not.

Medium power applications

Extend your ZENNIUM PRO potentiostat with a power potentiostat (PP2X2) for power applications (up to 200 W). The XPOT2 with a ZZENNIUM PRO potentiostat can be used as Bi-potentiostat especially for RDE, RRDE setups.
PP212
The external power potentiostat PP212 is used for medium power applications (up to 200 W) or in CIMPS system for controlling the light source. The PP212 is designed for currents up to ±10 A and voltage up to ±20 V.

PP222
The external power potentiostat PP222 is used for medium power applications (up to 200 W). The PP222 is designed for currents up to ±20 A and voltage up to ±10 V.

PP242
The external power potentiostat PP242 is used for medium power applications (up to 200 W). The PP242 is designed for high current measurement up to ±40 A and voltage up to ±5 V.

XPOT2
The compact external potentiostat XPOT2 adds an additional high precision channel to the ZENNIUM potentiostat for bi-potentiostat functionality e.g., for rotating ring disk electrode (RRDE) measurements. The XPOT2 provides currents up to ±500 mA and compliance voltage of up to ±25 V.

High power applications

Extend your ZENNIUM PRO potentiostat with our dynamic electronic loads (EL300/EL1000) for high power applications. Measurements with currents up to 680 A can be carried out for stacks with voltages of up to 100 V. Sine excitations of up to 1 kW can realize precise EIS measurement on large fuel cells, electrolyzers and battery systems.

EL1002
The dynamic electronic load EL1002 is optimized for EIS measurements on high power objects. It extends the power range of the ZENNIUM series potentiostats. Objects of up to 100 V can be characterized by EIS up to 100 kHz . In combination with third party devices the current range can be extended up to 680 A .

Probes

Equip your ZENNIUM PRO potentiostat with dedicated accessories for your required experiments like high impedance measurements (up to GΩ), low impedance measurements (down to µΩ) or high voltage measurements (up to 100 V) etc.

HiZ-Probe
The HiZ-Probe is used to optimize measurements on high impedance test objects (Impedance > 1 GΩ) or extremely low currents. The HiZ-Probe measures currents directly next to the sample and amplifies the signal to overcome electrostatic noise. Typical applications are investigations on passive layers, oxides, nitrides, dielectric films, ceramic substrates, low conductive electrolytes, lacquers, coatings, and microelectrodes etc. inside a faraday cage.

LoZ-Cable
The LoZ-Cable (length = 2 m) is specially designed for low impedance measurements like for batteries and fuel cells. The symmetric geometry of the cables significantly reduces the influence of mutual induction.

FRA-Probe
The FRA-Probe enables the ZENNIUM series potentiostats to interface and modulate third-party devices. It adds an additional dimension for EIS measurements on e.g., high power devices like automotive size single fuel cell measurements or large fuel cells stacks.

Addon Cards
The functionality of the ZENNIUM PRO potentiostat can be extended with addon cards. With extension cards additional analog and digital in- & output signals can be processed; power ranges can be optimized and extended.

EPC42
The EPC42 is the link between the ZENNIUM potentiostat and the power and auxiliary potentiostats or electronic loads. One EPC42 card can address up to four PP/EL/XPOT devices sequentially. Up to four EPC42 cards can be installed in a ZENNIUM X and ZENNIUM PRO potentiostat. In total, a ZENNIUM series potentiostat can be simultaneously connected with up to 16 external PPs/ELs, which can be controlled sequentially.

PAD4
A PAD4 card provides four additional voltage or current sense channels. The PAD4 card is primarily used for battery and fuel cell applications where impedance spectra or cyclic voltammograms for each cell can be recorded synchronous in a single measurement. The ZENNIUM X can be upgraded with up to four PAD4 cards which enables it to measure up to 17 impedance spectra in a single measurement.

RMUX16
The RMUX16 card allows to simultaneously connect up to 16 individual cells to the potentiostat. Up to four RMUX16 cards can be installed in a ZENNIUM series potentiostat which allows simultaneous connection to up to 64 electrochemical cells. The measurements on all connected cells are carried out sequentially. The RMUX16 card is an ideal addition for routine and screening measurements on small samples.

Multiplexer
Multiplexer simultaneously connects multiple test objects i.e., cells, with the ZENNIUM PRO potentiostats and allows sequential measurements on the connected cells. The automatic sequential measurements on several cells lead to significant increase in productivity and aid in automating the measurement routines.

PMUX-S
The PMUX-S power multiplexer is used to simultaneously contact the ZENNIUM series potentiostat with up to 16 individual cells. The measurements are carried out sequentially. For medium power applications, our power potentiostats can also be connected. The PMUX-S can be used for cell currents up to ±5 A.

BC-MUX
The battery cycling multiplexer BC-MUX is the link between the high power performances of your battery cycler and the EIS precision of our ZENNIUM potentiostats. The BC-MUX can address up to 16 channels to sequentially perform EIS measurements on the connected samples.  

Test stand integration

ZENNIUM PRO potentiostat can be controlled remotely and can be involved in a Python, C++ or Labview test stand.

Zahner provides its own Python GitHub repository which describes the incorporation of ZENNIUM potentiostat and its extensions in the Python lab environment.
