This EMF detector helps to measure the electromagnetic fields to identify appliances that produce high-level emissions, allowing users to make informed decisions about limiting exposure. With 5 LED indicators, which represent different radiation values. The 1st light (dark green) detects a normal EMF field, the range is between 0 to 1.5mG. The 2nd light (green) detects a low level EMF,which range is between 1.5 to 2.5mG. The 3rd light (yellow) detects a mid level EMF in the range between 2.5 to 10mG. The 4th light (orange) detects a high level EMF field in the range between 10 to 20mG. The 5th light (red) detects an extremely high EMF range of above 20mG.This EMF detector can instantly respond to EMF fluctuations and spikes, sensitive in detecting electromagnetic field. With clear LEDs, it is easy to read in the dark and in the sun. Featuring compact size, this EMF detector is portable, easy to use, rugged, reliable and super responsive. The UV reactive color paper is convenient for you to distinguish EMF value. This detector is usually used during ghost hunting and are also used for personal safety to identify potentially harmful high EMF radiation. It is known for its reliability and quality in the investigation of occult power. This makes the K2 EMF instrument an excellent tool for detecting mental activity and finding potentially harmful high EMF levels in a home or work environment.Made of high-quality ABS and metal, this radiation detector is durable.The length of this radiation detector is 14.3cm, the width is 5.3cm, the height is 2.9cm.This detector is used for the occult research or general EMF detection.Item Name: Radiation DetectorMaterial:ABS,MetalBatteries: 1 x 9V Battery 190mAh (Included)Size:14.3cmx5.3cmx2.9cm/5.63inx2.09inx1.14inNotes:Due to the light and screen setting difference, the item's color may be slightly different from the pictures.Please allow slight dimension difference due to different manual measurement.Package Includes:1 X Radiation Detector
