WinFIT Curve Fitting Software For Non-linear Models


WinFIT has been developed by NOVOCONTROL for researchers who wish to analyze dielectric and impedance spectra.

Advanced curve fitting techniques are used to ensure accurate and fast determination of material parameters.

Equivalent Circuit Analysis for impedance spectra is extended by arbitrary complex functions.

Special evaluations for dielectric measurements in polymer research are included like Havriliak Negami functions, Williams Landel Ferry (WLF), master plots and time domain conversion.
