1- Tri-Field Natural EMF Meter
A rather unique EMF meter as it detects changes in weak DC static fields after zeroing out, custom built with a red LED backlight. This meter is so sensitive that it can detect the amount of energy it takes to lift a grain of salt in a 10 'x 10' room. Adjustable tone control and a 50 hour lasting battery make this one of our favorites.

1- Ramsey TFM3C Tri Field EMF Meter
The center mounted three position switch on the Ramsay allows you to easily select electric, magnetic or RF fields. The zero out on the front panel allows you to set the sensors to a zero point for a clean starting point. A great choice when placed in front of a video camera and tripod ready.

1- Lutron 822-A Digital EMF Meter
This single axis digital meter measures ELF from 30-300 Hz. Large digital readout in mG or Tesla with accuracy within 4% at 50-60 hertz. Powered by a nine volt battery and a table top tilt stand embedded into the back of this meter, manmade fields in AC are a breeze to monitor. An article of this particular meter used in the field can be found here.

1- Cell Sensor With Probe
The CellSensor EMF/ELF meter requires the external probe otherwise it's only capable of detecting RF emissions found common with cell phones. Backlit and with an audible and visual alert this single axis gauss meter is calibrated for the 50-60 hertz range.

1- K-II EMF Meter
The KII is a thumb activated single axis EMF meter measuring both ELF (Extremely Low Frequency) between 50-1000 Hz and in VLF (Very Low Frequency) 1000-20,000 Hz. Originally popularized from Chris Fleming, as a guest investigator on Ghost Hunters, this 5 colored indicator lighting system can be found in most paranormal tool boxes.
