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.

Verkotan can now test eSIM devices with COMPRION’s solution!
In the future you will not probably need a physical SIM card. Instead, a SIM card will be embedded into your device. With COMPRION’s new eSIM Test Profile Service, Verkotan can now perform OTA and SAR measurements on eSIM devices! Read more
SAR Testing
New standard for SAR testing
IEC and IEEE have published a new standard, which includes some significant technical changes considering SAR testing. Among other things, the new standard broadened the SAR testing frequency range down to 4 MHz and up to 10 GHz. There are many common RFID and NFC devices that use these frequencies, and Verkotan is one of the few laboratories, who has the capability to test down to 9 MHz frequency. The standard has been mandatory in Canada since third of May 2021. Continue reading for more information! Read more
SAR Testing
Low Frequency SAR testing
Many consumer products, such as mobile phones and WIFI products, work in radio frequencies above 700MHz. However, there are many products that operate at low radio frequencies under 700MHz. Do you know how these low frequency devices are tested? Continue reading to find out how Low Frequency SAR testing is done step by step. Read more
