Isotropic electric and magnetic field probe - 1 Hz to 10 MHz: WP10M | Wavecontrol

The WP10M is an isotropic probe designed for electric and magnetic field measurement from 1 Hz to 10 MHz. It is intended for low-frequency and intermediate-frequency EMF exposure assessment in environments such as power grids, railways and industrial facilities.

The probe combines True RMS measurement, spectrum analysis capability and a 100 cm² sensor for detailed evaluation of electromagnetic field exposure. It supports both field strength measurement and Weighted Peak Method mode, enabling compliance-oriented assessment against occupational and public exposure limits.

Benefits

• Dual field measurement: measures both electric field and magnetic field with a single probe.
• Wide low-frequency coverage: full-band operation from 1 Hz to 10 MHz and low-band operation from 1 Hz to 400 kHz.
• Isotropic True RMS measurement: supports accurate assessment without requiring directional alignment of the probe.
• Spectrum analysis probe: FFT mode provides frequency analysis, total field and axis-based display.
• Compliance-oriented operation: supports standards and limits including EU Directive 2013/35/EU, IEEE, ICNIRP and BGV B11.
• Weighted Peak Method: suitable for assessing complex fields against exposure limits expressed as a percentage of limit values.
• ISO 17025 calibration: designed for professional EMF measurement programs requiring traceable calibration.

Why choose WP10M

The WP10M is a strong choice for technical teams requiring a single probe for low-frequency electric and magnetic field exposure assessment. Its wide 1 Hz to 10 MHz frequency range covers the main sources encountered in power distribution, rail systems, industrial installations and workplace safety evaluations.

By combining isotropic True RMS measurement, FFT spectrum analysis and Weighted Peak Method mode, the WP10M supports both diagnostic field investigation and regulatory compliance workflows. The probe is particularly suitable when measurements must be interpreted against recognized standards and exposure limits.
