The purpose of this article is a measuring parameters of a gaussmeter with a three-axis measuring probe designed for magnetic field mapping. Commercially available gaussmeters have low frequency bandwidth for these purposes, and signals cannot be measured in synchronous detec-tion mode. Therefore, a suitable magnetic field sensor was selected and one channel of the device was designed and made. In particular, the higher bandwidth for three-axis measurement and the possibility of synchronous signal detection were taken into account. Attention will also be paid to designing a suitable mechanical design of the probe and the location of the sensors. The gaussmeter will be used for magnetic impedance tomography (MIT), which is reconstruction method of con-ductivity image. On the proposed device was performed measurements of frequency bandwidth, noise measuring of Hall probe and measuring constants of Hall generators. The properties were evaluated and compared with parameters of commercially available Gaussmeters.
