These MATLAB-functions are ofted used for oxygen measurement experiments in professor Pasi Kallio's Micro- and Nanosystems Research Group (link). Scripts should be updated to MATLAB Apps format. Maybe in one day...
O2_MAIN_ChoosingWhatToDo.m opens window to choose what to do
Next, each possible choise is briefly presented
This will open window to start O2 measurement.

This will be used to run calibration.

This will be used to crop data

This will be used to plot different measurement data in different ways.

This will run functions that can be used to analyze measurement (step up or step down) properties.

I would like to thank D.Sc. (Tech.) Hannu Välimaki to provide Stern-Volmer equation and O2 sensor calibration functions.
