Why choose WPH60

The WPH60 is designed for users requiring a dedicated magnetic field probe for RF exposure assessment in the 300 kHz to 60 MHz range. Its high sensitivity, isotropic RMS measurement and flat response make it suitable for repeatable H-field measurements in controlled laboratory work, field inspections and occupational exposure evaluations.

Its compatibility with SMP2 and MonitEM allows integration into portable measurement workflows and monitoring configurations. The probe is particularly relevant when magnetic field exposure must be evaluated independently from electric field measurements.
