The PalmSens4 is a potentiostat and galvanostat with optional electrochemical impedance spectroscopy (EIS). It has low noise, high current resolution, and a large potential range. It is a complete laboratory instrument with a rugged design that is ideal for field work. This portable instrument has 4 GB of internal data storage and built-in Bluetooth communication which enables the device to be controlled with PSTrace PC software or an Android app called PSTouch. PSTrace is included with the instrument and PSTouch is available for free download in the Google Play store.

Available configurations:

  • Single Channel (see ordering tab below)
  • Multi Channel (4-10 individually customizable channels available. Ask BASi for quote)


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. The PalmSens4 is available in 6 different options with the specifications that are just right for your needs. The PalmSens4 is available as a bipotentiostat upon request and a multiplexer extension is available to convert it into an 8 or 16 channel instrument.
