K2 Flowmeter EMF Meter Five LED indicator light provides a clear, colorcoded reading of radiation values. The color scale is dark green 0 to 1.5 mgauss; green 1.5 to 2.5 mgauss; yellow 2.5 to 10 mgauss; orange 10 to 20 mgauss; red 20+ mgauss. Monitors 50/60 Hz frequency to assess EMF exposure and support Gauss testing. Used for monitoring radiation and safety to identify potentially harmful EMF radiation. Battery powered (battery not included) and reports EMF measurement values starting at 5 milligauss. Suitable for supernormal wave research and general EMF testing. Easy to read LED indicators in both darkness and daylight. Portable, easy to use, reliable and responsive. Use scenarios Home or office: quickly check EMF exposure around routers, computers, power strips, and other electronics to ensure safe levels. Industrial or construction sites: assess EMF near current equipment to identify potentially harmful exposure zones. Field research or safety: monitor environments for EMF radiation during activities or while evaluating equipment.
