The K2 or KII meter is an EMF (electromagnetic field)detection device.
When using this device, it is important to sweep all areas so you will know where "NOT" to think about paranormal activity. These areas include, but are not limited to, digital microwave displays, breaker boxes and the backs of refrigerators while they are running. High E.M.F. measurements can also be found near electric water heaters and digital alarm clocks. Cell phones will really mess with these devices so remember to turn your phone off while using the K2 meter.
