Description
Our flagship instrument, the PalmSens4, is a USB and battery powered Potentiostat, Galvanostat, and optional a Frequency Response Analyser (FRA) for Electrochemical Impedance Spectroscopy (EIS). The PalmSens4 has a large potential range (-5V to 5V or -10V to 10V) and current range (100 pA to 10 mA) with a high resolution and low noise. The economical PalmSens4 is a complete laboratory instrument but its compact and rugged design makes it also ideal for field work. Connecting via Bluetooth guarantees a perfectly floating measurement.
Configurable
PalmSens4 comes in different configurations:
- ±5 V or ±10 V potential range
- EIS/FRA with maximum frequency of 100 kHz or 1 MHz
- optional Bipotentiostat module for second WE
- optional iR-Compensation
Always a backup
Every PalmSens4 is equipped with an internal storage of 8 GB. This means all your measurements* can automatically be saved on-board as backup.
Measurements can be browsed and transferred to the PC easily using the PSTrace software for Windows.
*Not supported for on-device backup: EIS, MultiStep and MixedMode
PalmSens4 on-board the International Space Station
The PalmSens4 potentiostat is extremely robust and reliable and was selected for NASA expedition 63. It was launched into space on 9 April 2020 being part of a scientific experiment on-board the International Space Station.
