PalmSens MultiPalmSens4

The MultiPalmSens4 is a flexible multi-channel potentiostat, galvanostat and impedance analyzer which you can fully tailor to your requirements and budget. The MultiTrace software allows for using each channel individually or simultaneously or running a sequence of automated tasks on each channel. Each channel provides an additional auxiliary port for controlling peripherals or monitoring temperature or other analog signals. By enabling synchronization of channels and adjusting the setup of your cables, you can use the MultiPalmSens4 as a polypotentiostat. This means you can use multiple working electrodes, one counter and one reference electrode in the same cell at the same time. Your working electrodes all perform the same measurement.

The MultiPalmSens4 is customizable and has the options listed below.

Each channel can be configured with:

  • ±5V or ±10V maximum potential range
  • EIS/FRA with maximum frequency of 100 kHz or 1 MHz max
  • Bipotentiostat module for second WE
  • iR drop compensation
  • Galvanic isolation


Standard packaging includes a USB cable, crocodile clips, and a shielded cable with 2 mm banana connectors for a working electrode, counter electrode, and a reference electrode for each channel. MultiPalmSens4 channels are available in 6 different options with the specifications that are just right for your needs. MultiPalmSens4 channels are available as a bipotentiostat upon request and a multiplexer extension is available to convert each channel into an 8 or 16 channel instrument. Each channel is capable of running its own independent technique with individual parameters.
