PalmSens - Model 4 -Battery Powered Potentiostat
Our flagship instrument, the 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. The economical PalmSens4 is a complete laboratory instrument but its compact and rugged design makes it also ideal for field work.
- Potentiostat / Galvanostat / Impedance Analyzer
- FRA / EIS: 10 μHz up to 1 MHz
- 9 current ranges: 100 pA to 10 mA
- High resolution of 0.006 % full scale range
- 75 μV applied potential resolution (18 bit)
- potential range of ±5 V or ±10 V
- USB and battery powered

Available Configurations
The PalmSens4 is available with ±5V or ±10V DC-potential ranges and with different maximum frequencies for FRA / EIS. The following table shows the applicable product codes:
Standard included with a PalmSens4:
- Rugged carrying case
- High quality, double shielded cell cable with
2 mm banana connectors for Working, Counter, Reference electrode and Ground - Crocodile clips
- Dummy cell
- USB cable
- PSTrace software for Windows
Voltammetric techniques:
- Linear Sweep Voltammetry (LSV)
- Differential Pulse Voltammetry (DPV)
- Square Wave Voltammetry (SWV)
- Normal Pulse Voltammetry (NPV)
- AC Voltammetry (ACV)
- Cyclic Voltammetry (CV)
These methods can all be used in their stripping modes which are applied for (ultra-) trace analysis.
- Stripping chronopotentiometry (PSA or SCP)
Technique as a function of time:
- Chronoamperometry (CA)
- Pulsed Amperometric Detection (PAD)
- Multiple Pulse Amperometry (MPAD)
- Fast amperometry (FAM)
- Chronopotentiometry (CP)
- Open Circuit Potentiometry (OCP)
- Multistep Amperometry (MA)
- Multistep Potentiometry (MP)
- Mixed Mode (MM)
Impedance spectroscopy / EIS:
- Potential scan
- Time scan
Scans can be made at a fixed frequency or with a frequency scan.
- Fixed potential
Main extensions for PalmSens4:
- Multiplexer for using up to 8 or 16 cells with one potentiostat
- LM35 temperature sensor.
- Magnetic stirrer for stripping analysis applications.
- USB galvanic isolator for floating measurements.
- Differential Electrometer Amplifier (DEA) for use as floating voltage amplifier with differential input and single output for measuring an auxiliary signal between -5 to +5 V or -10 to +10 V.
