Palmsens 4 - Potentiostat, Galvanostat, EIS
The PalmSens4 serves as a USB and battery-powered Potentiostat, Galvanostat, and optionally a Frequency Response Analyser (FRA) for Electrochemical Impedance Spectroscopy (EIS).
With a wide potential range (-5V to 5V or -10V to 10V) and current range (100 pA to 10 mA), it boasts high resolution and low noise.
Economical yet complete for laboratory use, its compact and robust design also renders it ideal for field operations.
Bluetooth connectivity ensures accurate floating measurement.
Configurable options include potential range, EIS/FRA frequency, and additional modules. Every PalmSens4 includes a rugged carrying case, high-quality cell cable, crocodile clips, dummy cell, USB cable, and PSTrace software for Windows.
With 8 GB internal storage, all measurements are automatically backed up and easily accessible for data transfer and analysis.
A compact potentiostat with extremely high technological capabilities – the Palmsense 4 is a must-have device in every laboratory that performs electrochemical measurements.
