The WP400 is a low-frequency electromagnetic field probe designed for electric and magnetic field measurement from 1 Hz to 400 kHz.

It provides isotropic True RMS measurement and spectrum analysis capability for applications requiring accurate assessment of electromagnetic exposure in industrial, energy and railway environments.

The probe uses a 100 cm² sensor and is compatible with SMP3 and SMP2 field meters, making it suitable for field measurements, workplace exposure assessments and compliance-oriented EMF investigations.

Advantages

Electric and magnetic field measurement: one probe for E-Field and H-Field assessment in the low-frequency range.
Wide frequency coverage: measurement range from 1 Hz to 400 kHz.
Isotropic measurement: designed for 3-axis field assessment with reduced orientation dependency.
True RMS response: suitable for accurate broadband exposure measurements.
Spectrum analysis capability: FFT mode for frequency analysis, total field and axis display.
100 cm² sensor: adapted to exposure assessment requirements in low-frequency electromagnetic fields.
Standards-based evaluation: supports measurements in accordance with international standards and limits.
ISO 17025 accredited calibration: supplied with accredited calibration for traceable measurement confidence.
