Sensit Smart
Smartphone Potentiostat
- Capable of EIS up to 200 kHz
- Built around the EmStat Pico module
- Potential range -1.7 to +2 V
- Current ranges 100 nA – 5 mA (max ±3 mA)
Description:
The Sensit Smart is the smallest potentiostat available. You can directly connect the Sensit Smart toa smart phone or tablet and can be controlled via an Android app PStouch. You can alos connect it to your PC using a USB-C female to USB-A cable and then control it using the software PSTrace.
The Sensit Smart supports most common electrochemical techniques, including Cyclic Voltammetry, Square Wave Voltammetry and Impedance Spectroscopy (FRA/EIS).
Sensit Smart comes with-
- Dummy Cell (SPE Version)
- PSE 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)
- PStouch app for Android (find it in the Google Play Store)
