RelaxIS supports binary data formats from many manufacturers of measuring devices.

Files can be easily loaded by drag & drop into RelaxIS. This skips the need to first export and reprocess the measurement data before it can be used.

This functionality is continually developed, since it is an important factor in the increase of efficiency during everyday’s work.

RelaxIS manages not only raw impedance data, but also additional metadata like temperature, or DC bias for each spectrum. The data can be loaded from the file, or manually attached later. Metadata is used in various advanced evaluation features.

Spectra can be plotted in different views like Bode or Nyquist plots as well as in various transfer functions like impedance or admittance.

Combined plots of multiple spectra and 3D graphs can be created, allowing for an easy comparison.

All graphs can be exported into image or vector graphic files or as raw data.

An arbitrary number of spectra can be loaded into RelaxIS. Each spectrum can be assigned to one or more equivalent circuits.

The ease of testing different models for fitting your data improves the ability to explore possible interpretations of the measured processes.

Besides all common equivalent circuit elements, RelaxIS also features common Transmission Line Models (TLM) and a custom TLM-builder.

Further user-defined elements can be added via the RelaxIS plugin system, that allows you to program your own models in C# or VB.NET.

RelaxIS offers powerful tools to initialize fits, like painting shapes into the data or a genetic algorithm to assist in the initialization of the parameters.

In addition, it is possible to evaluate particular types of spectra fully automated using the fit wizard. These include conductivity measurements or battery spectra. Here, only minimal user interaction is necessary.

If larger data sets are analyzed, a batch fitting routine can be applied. It enables the evaluation of related spectra with only a single adjustment of the initial values. Depending on the application, the analysis of several dozen spectra per second is possible.

Tired of manually adjusting parameter values until the fit works? The RelaxIS Auto Fit feature does it for you. Simply choose a model, and the Auto Fit takes care of the rest.

Employing a powerful genetic algorithm optimized for use with EIS spectra, most models can be fitted very reliable out of the box.

For the very hard cases you can take full control over the parameters.

RelaxIS can calculate the distribution functions of time constants for your spectra. Multiple spectra can be selected at a time for batch processing.

In the DRTs you can perform peak-picking and integration and export these results for further use.

RelaxIS 3 allows you to further evaluate the model parameters you obtained from fitting to equivalent circuits.

The parameters can be plotted, recalculated and fitted as a function of metadata variables such as temperature or DC bias.

This allows for example the fitting of temperature dependent data to VFT- and Arrhenius-models, but extends the functionality of RelaxIS 2 by allowing other, arbitrary models as well.

A fast and easy export of the data into other applications is essential. For this purpose, RelaxIS provides extensive possibilities to export the various data into easy-to-use data formats. 

In addition to the raw data export into text files it is also possible to create rich reports about the evaluated spectra.

These reports are fully customizable and can contain graphs, evaluation results or metadata about the spectra.

The reports are HTML based and therefore very flexible.

RelaxIS Remote allows you the completely autonomous evaluation of measured data.

Data can be sent from external devices through either FTP or WCF connectivity to RelaxIS.

The data is then evaluated and stored based on settings defined by the sender. Afterwards the results can be sent back to the sender as raw data and/or reports.
