The Cemprotec 33 electromagnetic wave detector allows you to quickly and easily check your level of exposure to high frequency (5G, Wifi, etc.) and low frequency electromagnetic waves (electricity, high voltage power lines, electrical transformers, etc.).
Thanks to its intensity reading scale made up of 21 colored LEDs, the Cemprotec33 electrosmog detector instantly and precisely displays the level of low and high frequency electromagnetic radiation. The Cemprotec33 electromagnetic wave detector is therefore dedicated to individuals wishing to know easily and quickly their degree of exposure to electromagnetic pollution.
Cemprotec33 low and high frequency wave detector description
The Cemprotec 33 high and low frequency electromagnetic wave detector is very easy to use. On the same device, thanks to colored LEDs, Cemprotec33 allows rapid assessment of electromagnetic pollution due to low-frequency electric and magnetic fields and that due to high-frequency electric fields.
A "full HF" mode allows increased precision in the detection of high frequency electromagnetic waves. Its wide frequency range allows Cemprotec33 to detect: 2G, 3G, 4G, 5G mobile telephone networks, mobile telephone relay antennas, Wi-Fi, DECT household cordless telephones, FM broadcasting, television broadcasting, ... but also low-frequency electromagnetic waves due to electric current, electric transformers, LV, HV power lines, ...
Robust, very easy to use, compact, the wave detector Cemprotec-33 can accompany you everywhere. The Cemprotec33 electromagnetic wave detector is a new, more advanced version of the ESI23 and ESI24 wave detectors.
