Description
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.Â
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 Extension cable
- USB-C port protector
- PSTrace software for Windows (activation code for my.palmsens.com)
- PStouch app for Android (find it in the Google Play Store)

| [1]Â 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.

< 0.2% |
Current ranges
A potentiostat measures current. For optimal precision, the range between which currents are measured is split into multiple current ranges. A current range defines the maximum current a potentiostat can measure in a certain range. This means it will also determine the resolution, because the number of bits or rather states is fixed, while the current range is variable.

100 nA to 5 mA (10 or 12 ranges, depending on the mode) |
| Current resolution | 0.006% of selected current range (5.5 pA on 100 nA range) |
Current accuracy
The current accuracy describes how close to the real values your measured current is.
|

Electrometer amplifier input
The amplifier input resistance of the amplifier in the electrometer determines the load that the amplifier places on the source of the signal being fed into it. Ideally the resistance is infinite, and the load to be zero to not to influence your measurement.
