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, allowing testing anywhere. Wide Applications: Electromagnetic radiation detectors can measure sources such as air conditioners, induction cookers, rice cookers, refrigerators, computers, and wires. Sound and Light Alarm: When the detection result exceeds the safety threshold, the EMF meter will automatically trigger an alarm. As the radiation level increases, the alarm sound frequency increases. Radiation Assessment: EMF detectors help you better understand electromagnetic fields (EMF) and how to minimize exposure. This meter can detect both electric and magnetic field radiation. Easy Operation: The radiation tester clearly indicates whether the current radiation level is within a safe range. Its sleek design allows for convenient one-handed operation, making measurements simple and efficient. Color: Yellow Material: Plastic Size: Approximately 12.5 x 6 cm Package Contents: 1 x Electromagnetic Radiation Tester Note: Light reflection and different displays may cause the color of the item in the picture to appear slightly different from the actual product. Measurement error allowance is +/- 1-3 cm.
