Isotropic E&H Field Probe 1 Hz – 10 MHz : WP10M | WAVECONTROL
WP Series isotropic True RMS E&H field probes from 1 Hz to 10 MHz. FFT analysis, Weighted Peak Method, ISO 17025 calibration, compliant with EU Directive 2013/35/EU and IEC standards.
close
The WP Series consists of professional combined electric and magnetic field probes designed for low-frequency and broadband applications from 1 Hz up to 10 MHz, depending on the model. The probes support True RMS measurements, FFT spectrum analysis and Weighted Peak Method (WPM) for human exposure compliance assessment. All probes are delivered with ISO 17025 accredited calibration (ILAC).
