The Sensit Smart is the world smallest ready-to-go potentiostat available on the market. The Sensit Smart can be directly inserted in a smartphone or tablet and controlled via the Android app PStouch. You can use the USB-C Female to USB-A cable to connect the Sensit Smart to a classic USB port on your PC and control the Sensit Smart via our PC software PSTrace.
The Sensit Smart supports most common electrochemical techniques, including Cyclic Voltammetry, Square Wave Voltammetry and Impedance Spectroscopy (FRA/EIS).
The Sensit Smart comes with:
- Dummy Cell (SPE version)
- SPE to screw-terminal adapter
- USB-C Female to USB-A cable
- USB-C Female to Micro USB adapter
- USB-C port protector
- PSTrace software for Windows (activation code for my.palmsens.com)

EmStat Pico module
Techniques
The following techniques are supported by the Sensit Smart
Voltammetric techniques:
- Linear sweep voltammetry (LSV)
- Cyclic voltammetry (CV)
- Square wave voltammetry (SWV)
- Differential pulse voltammetry (DPV)
- Normal pulse voltammetry (NPV)
These methods can all be used in their stripping modes which are applied for (ultra-) trace analysis.
Techniques as a function of time:
- Chronoamperometry (CA)
- Pulsed amperometric detection (PAD)
- Open circuit potentiometry (OCP)
- Multistep amperometry (MA)
Electrochemical Impedance Spectroscopy:
- Scanning or fixed frequency mode (EIS)
Specifications
The Sensit Smart works at three different modes;
- Low Speed mode: for scan rates up to 1 V/s or a bandwidth of 100 Hz.
- High Speed mode: for high scan rates and frequencies.
- Max Range mode: a combination of the Low and High Speed modes for optimal dynamic dc-potential range.

[1] The dynamic range is the range that can be covered during a single scan within the full potential range. For example; a linear scan can start at -1.5 V and end at 1.1 V or vice versa, covering 2.6 V dynamic range.
[2] The compliance voltage is the maximum potential between Working and Counter electrode and depends on the selected mode.
