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.<br><br>Electric field Measure Range: 1-1999V/m Magnetic field Measure Range: 0.1-999.9mG Radiation field Measure Range:0.1-999.9mW/m² EF (electric field) sensitivity: 1V/m MF (magnetic field) sensitivity: 0.1mG RF (radio frequency) sensitivity: 0.1mW/㎡ Measurement accuracy: ±5% Measurement bandwidth: 40Hz-10GHz Auto shutdown: 15 minutes Working: temperature: -10-+60℃; Working humidity: Less than 80%RH Battery: 320mAh lithium battery Charging voltage: DC5V Charging current: Less than 1A Colour:Black & Green Material:ABS Due to different batches, there may be differences in product appearance and printed text, which will not affect use<br><br>Package Contents: 1 * RD600S EMF Meter 1 * Lanyard 1 * Charge cable<br><br>Only the above package content, other products are not included.
