Compact design: This digital camera is suitable for travel, psychological research, visitor and hotel inspection. The portable design is easy to carry and store, and can be tested anywhere. Widely used: Electromagnetic radiation detectors can measurehousehold appliances, such as televisions, air conditioners, induction cookers, rice cookers, refrigerators, computers, wires and other supernatural equipment. Audible and visual alarm: when the detection result exceeds the safety value, it will automaticallyalarm. As the radiation value increases, the frequency of the alarm will increase. Radiation assessment: EMF detectors help you better understand electromagnetic fields (EMF) and how to minimize EMF exposure. The EMF meter can test the radiation ofelectrical and magnetic amplifiers. Simple operation: the radiation tester closely reminds us whether the current radiation value is safe. It is smooth, easy to use with one hand and convenient for on-site measurement.
