E.L.F. Zone EMF Meters

     These are inexpensive AC EMF meters. They are highly sensitive to moving DC EMF fields as well as AC fields, and have a wide frequency response. They only have a 2 LED resolution (+2.5mG, +7mG), but the amplification is very clean. When the analog output is tapped, they make a good laboratory meter to use with an oscilloscope, etc.
