Multiple field "Natural" EM / MICROWAVE meter measures LOW static electric, radio-microwave and magnetic fields (skyborne magnetic sources, surveillance "bugs", electrical fields carried by humans &
animals).
The TriField Natural EM Meter detects changes in extremely weak static (or natural") electric and magnetic fields. It signals with both a tone and the movement of a needle-type gauge if either the electric or magnetic field changes from previous levels.
A radio and microwave detector is also included, which reads radio power directly if any transmitters are nearby. Since man-made AC electric and magnetic fields are very common and could interfere with readings of static fields, the meter has
been designed to ignore the AC fields of power lines, appliances, etc.
This meter was designed to satisfy the need for natural field measurements in specialized research areas. It can detect
"geomagnetic storms" caused by unusual solar activity interacting with the ionosphere (which results in rapid changes of up to
10% in the Earth's magnetic field), as well as the electrical activity of ordinary thunder storms. Ball lightning should in theory be
associated with a strong magnetic field, and magnetization of metal has been reported with some UFO sightings. When set on
MAGNETIC, the Natural EM Meter will signal the movement of any strong magnetic source in the sky, even if the sky is
cloudy or the source dips behind a hill. Since construction materials generally do not block magnetic fields, the meter can be placed indoors and work equally well. The built-in tone allows its use in the dark.
The meter is sensitive to changes of as little as 0.5% of the strength of the Earth's magnetic field, and the tone will sound
whether the field increases or decreases. If the magnetic field then becomes stable for more than about five seconds, the tone
will stop and the needle will return to zero. The meter remain at rest until the field changes again. The threshold level, or
"squelch", of the tone is adjustable. The user determines the amount of change in the magnetic field (within a 0.5 second
interval) required to sound the tone. If the field changes by the threshold amount, the tone will come on at a low pitch If the
amount of change is large, the tone's will be higher.
When the dial is set to ELECTRIC, the meter is sensitive to electric
fields as weak as 3 V/m (volts per meter). To illustrate just how
feeble a field this is, a l0'xl0'xl0' room filled with a field of this
strength has a total amount of energy equivalent to that required to
lift a single grain of table salt 1/50th of an inch. Indoors, electric
fields typically fluctuate 1 or 2 V/m. By setting the minimum
sensitivity to change at 3 V/m, we have designed the meter to disregard
this "background noise".
Human beings and animals usually emit an
electric field which is easily detectable using the Natural EM Meter.
In fact, the meter can be used as a motion-activated intruder alarm. It
is so sensitive that it can detect the presence of a person through a
wall. Though it is not foolproof in this capacity, (sometimes a person
will carry NO electric charge and thus be "invisible" to the meter),
it's sensitivity is of interest to researchers in the field of
parapsychology, especially "ghost hunters". Every type of detectable physical manifestation
requires a certain amount of energy. For example, "moving air" requires the expenditure of a small amount of energy to get the air to move initially.
Below is a table showing several types of effects or fields emitted by people and objects. It also shows the minimum amount of energy required (per cubic foot of air) to set up that effect or field so that it is stronger than typical indoor "background noise" for that effect or field. Clearly the static electric field is the type that requires the least energy to be detectable.

(watts-seconds) Are instruments needed
to detect this?
The radio/microwave detector is sensitive from 100,000 to 2.5 billion oscillations per second (100 KHz to 2.5 GHz) and can detect strong or unusual atmospheric electrical activity. It can also detect leaky microwave ovens, cellular or portable phones, walkie-talkies and concealed surveillance bugs. Its minimum and maximum detectable signal strengths are 0.01 milliwatt/cm2 and 1 milliwatt/cm2 respectively.
