This is a powerful portable EMF detector with multiple functions. It can detect three types of non-ionizing radiation electric field (EF) 1-1999V/m, magnetic field (MF) 0.1-999.9mG or 0.01-99.99uT, and radio frequency () 0.1-999.9mW/㎡ or 0.01-99.99uW/c㎡. In addition to the numerical display, the three-color backlight and bar graph provide additional visual assessment of radiation intensity. Built-in high-capacity lithium battery, Type-c charging port, USB cycle charging. Three types of radio frequency radiation () can be identified: WIFI/PHONE (WIFI radiation), MICROWAVE (microwave radiation), MIXED (mixed electromagnetic wave radiation). The instrument has a built-in 3- magnetic field radiation receiving antenna, which can detect XY/Z three- magnetic field radiation (MF), identify the direction of magnetic field radiation, and display it on the screen. Portable design: The electromagnetic radiation detector adopts a portable design, which is compact, , easy to carry and operate, and suitable for on-site testing and mobile measurement., Weight: 0.54123485321 Pounds, Manufacturer: NONDK
