Software

PSTrace

PSTrace is designed to be productive immediately after installation, without going through a long learning period. It has three modes; the Scientific mode which allows you to run all the techniques our instruments have to offer, and two dedicated modes for Corrosion analysis and the Analytical Mode. PSTrace is suitable for all levels of user experience.

Features include:

  • Direct validation of method parameters
  • Automated peak search
  • Equivalent Circuit Fitting
  • Scripting for running an automated sequence of measurements
  • Open data in Origin and Excel with one click of a button
  • Load data from the instrument’s internal storage
  • and many more…

Software Development Kits

PalmSens provides several Software Development Kits (SDKs) to help developers create custom software to control their potentiostat. Each SDK comes with documentation and examples that shows how to use the libraries.

SDKs are available for:

  • .NET (WinForms, WPF and Xamarin for Android)
  • Python
  • LabVIEW
  • Matlab
More information about SDKs for .NET

MethodSCRIPT™ Communications Protocol

The Sensit-series work with MethodSCRIPT™, giving you full control over your potentiostat channels. The simple script language is parsed on-board, which means no DLLs or other type of code libraries are required. MethodSCRIPT™ allows for running all supported electrochemical techniques, making it easy to combine different measurements and other tasks. 

MethodSCRIPT can be generated, edited, and executed in PSTrace.

MethodSCRIPT features includes:

  • (Nested) loops and conditional logic support
  • User code during a measurement iteration
  • Exact timing control
  • Simple math operations on variables (add, sub, mul, div)
  • Data smoothing and peak detection
  • Digital I/O, for example for waiting for an external trigger
  • Logging results to internal storage or external SD card
  • Reading auxiliary values like pH or temperature
  • and many more…

Compatibility
