Verkotan provides Electromagnetic Field Measurements (EMF) for RF exposure evaluations. We measure with EMR-300 E-field from 100 kHz to 3 GHz and H-field from 27 MHz to 1 GHz and with Narda EHP-200 E/H-field probe from 3 kHz to 30 MHz.
We measure according to following requirements / standards
- EU: Reference level measurements for electric and magnetic fields (according to EN 62311 and council recommendation 1999/519/EC)
- USA: RF exposure measurements for low frequencies according to KDB 680106 D01 (RF exposure considerations for low power consumer wireless power transfer applications)
- Canada: SPR-002 — Supplementary Procedure for Assessing Compliance with RSS-102 Nerve Stimulation Exposure Limits
Public concern about the possibility of health risks resulting from exposure to electromagnetic fields (EMFs) emitted from various wireless devices and their infrastructure continues to be an issue all over the world. It is essential that public is not exposed to dangerous levels of electromagnetic radiation, and thus EMF measurements are performed to ensure a device’s compliance to international guidance.
Verkotan provides EMF measurements for radio frequency exposure evaluation. E-field is measured in frequency range of 3 kHz–3 GHz and 3 kHz–1 GHz for H-field.

When to show RF exposure compliance with calculations
RF exposure compliance of electronic and electrical equipment with the basic restrictions, or with the reference levels, is usually determined by testing. However, if the product meets certain requirements, the RF exposure compliance can be shown by calculations without any testing. Continue reading for more information about RF exposure calculations.
