HFD-0191 FieldMan H-Field probe, 27MHz - 1GHz

The probe detects magnetic fields from 27 MHz up to 1 GHz. This wide frequency range for a magnetic field probe covers all the major areas of electromagnetic field exposure that can occur in radio and TV broadcasting, telecom-munications, and in high frequency industrial applications. The probe is suitable for the detection of human exposure limits in the general public and occupational environments.

The probe's interface digitally transmits the measurement data to the base unit, which has no individual influence on the measured values and therefore does not need to be calibrated. Probe calibration is carried out at several frequencies. The calibration data is stored in the probe and is automatically taken into account during the measure-ment. If the frequency of the predominating field strength is known, a correction factor can additionally be applied to increase the measurement accuracy.
