The Microrad 30H probe is based on a set of three mutually orthogonal Hall sensors. The three voltages, which correspond to the spatial components of the field, are available individually at the probe output. The NHT 310 or NHT 3D meter calculates the resulting isotropic field strength. The 30H probe detects magnetic fields from 0 to 1000 Hz. It is suitable for use in applications such as Magnetic Resonances Imaging (MRI), materials working plants (galvanic and mills) and power supply plants for railway stations. The high sensitivity of this probe makes it ideal for exposure measurements in sensitive environments, such as places where people using peacemakers are present. The presence of a first-order high-pass filter (20 dB / decade) with a 1.5Hz cutting frequency allows to discriminate the static component from the others at higher frequencies. In fact, the filter, when inserted, completely suppresses the continuous component and the probe band becomes 1.5 Hz ÷ 1000 Hz.
