Electric and magnetic field probe - 10 Hz to 3 kHz, weighted response: WP50 | Wavecontrol

The WP50 is an isotropic probe designed for combined electric and magnetic field measurement from 10 Hz to 3 kHz. It supports True RMS measurement and can be used in both weighted mode and flat response mode, depending on the selected measurement requirement.

The probe is intended for low-frequency electromagnetic field assessment in power grid, railway and industrial environments. It is designed for measurements in accordance with IEC 62110 and IEC 61786, with exposure evaluation based on public and occupational ICNIRP 2010 limits in weighted mode.

Benefits

• Combined E-field and H-field measurement: simultaneous assessment of electric and magnetic fields with one probe.
• Low-frequency EMF coverage: measurement range from 10 Hz to 3 kHz.
• Isotropic True RMS measurement: suitable for real field environments where direction and signal behaviour may vary.
• Weighted measurement mode: results displayed as a percentage of the selected exposure standard.
• Flat response mode: field strength displayed in engineering units such as V/m and µT.
• 100 cm² field sensor area: suitable for low-frequency exposure measurements around power grid and railway infrastructure.
• Accredited calibration: ISO 17025 accredited calibration with ILAC recognition.
