PalmSens4

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. This instrument is a complete laboratory instrument but its compact and rugged design makes it also ideal for field work.

  • potential range: ±5V or ± 10V
  • compliance voltage: ± 10V
  • current ranges: 100 pA – 10 mA
  • maximum current: ± 30 mA
  • max freq. for EIS: 100 kHz or 1 MHz

PalmSens4 is shipped with the new PSTrace 5.0 software.
New in PSTrace 5.0:

  • Equivalent Circuit Fitting and Simulation for EIS
  • Support for PalmSens4; view and copy data on its internal 4GB storage
  • New technique: Mixed Mode for combining potentiometry and amperometry, potential sweeps and measuring at open circuit
  • Improved UI
  • New “.pssession” file format introduced for always saving all available measurements, method information and meta data to a single file.
