Specifications
The module 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.
The compliance voltage is the maximum voltage that can be applied between the working and counter electrode. Another name could be the maximum cell potential. Continue reading

Software Development
Develop software for PC, smartphone or microcontroller
Whether you want to write a simple or advanced Windows application, develop an Android or iPhone app or integrate the EmStat Pico in your own hardware, you can do it with our software development tools and code examples.
The EmStat Pico Development Board can also be controlled directly with our PSTrace software for Windows and PStouch app for Android.
Software Development Kits for .NET
The PalmSens Software Development Kits (SDKs) for .NET can be used with any of our instruments or OEM potentiostat modules to develop your own software. The SDK’s come with a set of examples that shows how to use the libraries.
PalmSens SDKs with examples are available for the following .NET Frameworks:
- WinForms

- Xamarin (for Android)
- UWP
MethodSCRIPT™ communications protocol
The EmStat Pico potentiostat module has an on-board parser for the MethodSCRIPT™ scripting language. This language allows developers to program a human-readable script for the EmStat Pico module on any platform or operating system. The simple script language allows for running electrochemical techniques supported by EmStat Pico and makes it easy to combine different measurements and other tasks.
