protect yourself from high frequency EMR
Very interesting device. My WiFi access point measures 12 Volts per meter (V/m) right above and 0.437 V/m or 437 mV/m two meters away. Or in microwatts per centimeter squared (μW/cm2) = 33 μW/cm2 above and 0.031 μW/cm2 2 meters away. These values were determined by using the MAX function of the display. Bioinitiative.org determined in 2007 that 0.1 μW/cm2 was the maximum value acceptable for the public but revised that value downwards in 2014. Seeing these values I switched my WiFi off and use only the cable to the LAN network. (RJ-45 connector). I then only have the background radiation from my neighbors that amount to 9 mV/m or 0.15 μW/m2 (not measurable per cm2). The cell phone mast at my local train station emits 2.7 V/m. Around this mast (30 meters high) nature appears to be stone dead : no birds, cats insects or other sign of life). So with this meter you can investigate your own surroundings but the new frequency of 5.8 GHz can not be measured as the range of this meter goes from 50 MHz to 3.5 GHz.

Perfect for use in the mirror universe.
Seriously, what does that mean. It's printed on a sphere. Why not just indicate the directions of the axes in the actual physical directions. Instead, there's a 2d projection of a 3d reference frame that can't actually mean anything. Also, it's a LEFT HANDED coordinate system! WTF?!
