MultiPalmsens4

  • 4 to 10 channels available in different configurations
  • FRA / EIS: 10 μHz up to 1 MHz
  • 9 current ranges: 100 pA to 10 mA
  • potential range: ±5 V or ±10 V

 

Description:

The MultiPalmSens4 is a multi-channel potentiostat, galvanostat and impedeance analyzer. The MultiTrace software allows for you to use 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.
