The THM1176 from Metrolab is the reference instrument for measuring magnetic fields in magnetic resonance imaging (MRI) rooms. It is the only family of 3-axis portable Hall magnetometers on the market. It combines the performance of a professional Hall instrument with the ease of use of a USB device. It simultaneously measures the three axes of the magnetic field (Bx, By, Bz), allowing precise reading of field intensity regardless of probe orientation.
