This thesis deals with designing a portable indicator for measuring of content of ferromagnetic phase in non-ferromagnetic steels. The first part of the thesis describes the principle of sensor used in the indicator. A market survey is presented, with a description of selected indicators that are suitable for measurement of content of ferromagnetic phases. The following part deals with a design of the device hardware, which is focused on finding a suitable indicator concept. Circuits for battery charge, measuring chain and other circuits are designed in this part. The following part of the thesis describes the function of the software. First it describes the software for DSP, then the software for personal computer. The software for DSP has been programmed in the C language, the software for the personal computer in the C# language. The last part but one describes an inspectional measurement of the indicator. This measurement has been performed on testing samples as well as other materials. The final part presents a summary of the outcomes and provides recommendations for possible improvement.
