Description

The EmStat4M Development Kit is equipped with a research-grade potentiostat module, which delivers desktop performance. The EmStat4M is a potentiostat/galvanostat supporting Electrochemical Impedance Spectroscopy (EIS). The EmStat4M Development Kit can be used with PSTrace for Windows. You can write your own applications for the EmStat4M Development Kit using our .NET libraries for Windows and Android or using MethodSCRIPT™ and control it from any platform or operating system.

Versions

The EmStat4M Development Kit comes with two different versions of the EmStat4M potentiostat module:

  • Low Range (LR): current range from 1 nA to 10 mA, max. 30 mA
  • High Range (HR): current ranges from 100 nA to 100 mA, max. 200 mA

See specifications for more information.

Always a backup

Always a backup

The EmStat4M is equipped with 500 MB internal storage memory for storing your measurements and meta data. All internally stored measurements can be browsed and transferred back to the PC easily using the PSTrace software for Windows or with your own software.

Included in the EmStat4M Development Kit

The Development kit includes a sensor cable, software, a Development Board (PCBA) and more. The Development Board offers extra peripherals including:

  • Bluetooth module (Laird BT900)

Software Development Kits

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
  • WPF
  • Xamarin (for Android)
More information about SDKs for .NET

MethodSCRIPT™ communications protocol

The EmStat4 potentiostat module has an on-board parser for the MethodSCRIPT scripting language. This language allows developers to program a human-readable script for the EmStat4 module on any platform or operating system. The simple script language allows for running electrochemical techniques supported by EmStat4 and makes it easy to combine different measurements and other tasks.
