Détecteur de champ électromagnétique (CEM), détecteur portable 30-20 000 Hz, appareil de mesure des CEM paranormaux avec affichage LED multi-segments

Reliable detection and identification of equipment emitting high levels of electromagnetic radiation, with a detection frequency of 30 to 20,000 Hz and a detection range of 0 to over 20 milligauss. This sensitive detector can detect high, medium, and low-frequency electromagnetic fields, enabling you to quickly make informed decisions to limit exposure. Easy-to-read multicolor LEDs indicate the radiation level: green for normal and low levels, yellow for risk areas, orange for high levels, and red for alert areas. Powered by a 9V battery (included), it offers high efficiency and low power consumption. Dimensions: 19 x 4 x 2.5 cm. Compact and easy to use and carry. Note: If the LED brightness decreases or does not light up, replace the battery. Package contents: 1 EMF detector, 1 x 9V battery. Measuring electromagnetic field levels helps prevent potential risks associated with prolonged overexposure. Spectrum detector for Halloween, electromagnetic field detector for home, office, and outdoor use.
