Compact Design: This digital EMF meter is compact for travel, parapsychological research, visitors, and hotel inspections. The portable design is easy to carry and store and can be tested anywhere.Wide Applications: Electromagnetic radiation detectors can measure household appliances such as TVs, air conditioners, induction cookers, rice cookers, refrigerators, computers, wiring, and other paranormal equipment.Sound and Light Alarm: When the detection result exceeds the safety value, the EMF meter will alarm automatically. As the radiation value increases, the frequency of the alarm sound will be higher.Radiation Assessment: EMF detectors help you better understand electromagnetic fields (EMF) and understand how to minimize EMF exposure. EMF meters can test both electric and magnetic radiation.Easy Operation: The radiation tester intimately reminds us whether the current radiation value is safe. It is elegant and convenient to operate with one hand, making it easy to measure in the field.Color: yellowMaterial: plasticSize: approx. 12.5 x 6 cmPackage Contents:1 * Nuclear Radiation DetectorOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
