RD600S EMF Meter is an electric field(EF), magnetic field(MF), and radio frequency field(RF) 3-in-1 multifuctional meter. It is equipped with a build-in electromagnetic radiation sensor, which can display tha radiation value on LCD screen after processing by the micro-control chip. You can make reasonable processing or take effective prevention measures toward the electromagnetic radiation according to the test result. [Widely used]Home, office, outdoor, industrial,Mobile phone, computer,TV, refrigerator high voltage line radiation detection;Test the effect of protective equipment such as radiation protective clothing and radiation protective film, also used on ghost hunting filed.
