WPF18 Field Probe
WPF18 Field Probe
The Wavecontrol WPF18 isotropic electric field probe measures RF field strength from 300 kHz to 18 GHz with true RMS detection. It provides 0.5–250 V/m (CW) and 0.5–30 V/m (RMS) measurement ranges with 0.5 V/m sensitivity and 54 dB dynamic range.
Used to measure electric field strength, power density, and RF exposure levels, this probe is commonly applied in telecommunications audits (GSM, 3G, LTE, AM/FM, Wi-Fi), industrial RF process assessments, defense site compliance, and research lab personnel protection. The WPF18's high sensitivity (0.5 V/m) makes it ideal for low-level background measurements and compliance verification where precision matters.
Common applications: cell sites and broadcast transmitters, radar and aerospace, R&D labs, RF heating and drying, diathermy and electrosurgery, and railway communications. See EMF measurement by industry for the standards that apply.
