AlphaLab Trifield EMF Meter
Electromagnetic Field
Detector
|
 The
Trifield EMF Meter is an excellent tool. It has three
different types of detection and four settings. The
first two settings measure magnetic fields, with a
detection range of 0-100 and 0-3 milligauss
respectively. The third measures electric fields in the
0-100 kilovolts/meter range, and the radio/microwave up
to 3GHz. The 0-3 magnetic setting is so sensitive that
many normal household appliances will send it off the
scale. For that reason, we normally use the 0-100 range
unless we are in a location with absolutely no
electricity. We tend to use magnetic over electric due
to the fact that it seems to encompass a wider range of
detection. Electrical objects will typically generate a
magnetic field, while something magnetic will not
necessarily generate an electrical field.
This Trifield has had several modifications added by the
factory. The top left switch toggles LED backlighting
on and off. This makes it extremely nice for dark
investigations as trying to hold a flashlight on an
unlit meter can be distracting to you and everyone
around you, not to mention it frees up a hand. The knob
on the right controls the audible alarm. When
activated, it is used by turning the knob until just
before the sound is heard, or lower if the desire is to
only pick up more dramatic spikes. This sets the
background level so that it will sound only when the
meter detects a reading higher than what the alarm is
set at. This makes it possible to set the meter down on
the other side of the room without losing functionality. |
Alphalab Trifield Natural EM Meter
Electromagnetic Field
Detector |
 Like
the Trifield above, this device detects electromagnetic
fields. Unlike the Trifield above, it is designed to
ignore fields generated by man-made objects. The scales
are the same, with the exception of a sum setting
replacing the 0-3 magnetic range. The sum setting
combines both the electric and magnetic settings to
detect changes in either field. While we have added LED backlighting to this as well, the alarm
knob comes standard.
Using this meter is a little different than that of the
standard Trifield. Due to the fact that the magnetic
setting extremely sensitive to Earth's natural magnetic
field, using it while moving will produce very unstable
readings. This means that ideally it is placed across
the room using the sum setting with the alarm set to
just above the current background level.
The electric setting is designed to be so sensitive that
it can reliably detect humans and animals from up to 10
feet away. While we have not been able to detect humans
from more than 2 inches away, we have noticed that it is
very sensitive to static electricity stored in plastic
surfaces such as tarps and trash bags.
One thing to note is that there are two models of the
Natural EM meter. The Model 2 adds an AC power adapter
while the Model 1 is battery only. They are very
similar on the surface but the model 2 has a very
important difference: the sum setting combines magnetic
and radio/microwave detection, instead of the electric
and magnetic combination on the Model 1. This makes the
Model 1 much more useful for paranormal investigations. |
Sperry EMF-200A
Electromagnetic Field
Detector |
 This
device is referred to by many people as simply an 'EMF
Meter' due to being one of the more common detectors in
use by paranormal investigators today. It has a range
of 0.1-199.9 milligauss and is extremely simple to use
and understand due to the digital readout on the LCD
screen. One huge benefit of the Sperry is that,
unlike most EMF meters, it is unaffected by radio
frequencies. The downside is that it has no backlighting,
meaning much of the time a flashlight is needed in order
to see it during investigations. It is a very useful
tool for familiarizing oneself with how electromagnetic
fields work and what causes them.

"Ghost Meter"
Electromagnetic Field
Detector |
 An
inexpensive EMF meter that makes a decent backup or
starter for those that cannot afford a Sperry or
Trifield. It has a detection range of 0-5 milligauss
and the light will flash at a rate based on the
reading. This can make it useful for leaving in a room
with a video recording system as it would be impossible
to get a camera to focus on the LCD of a Sperry and
still get a good view of the room. It might not give
you much information on what was going on, but it would
at least indicate you to the fact that something was
happening.

K-II Meter
Manual Electromagnetic
Field Detector |
 The
K-II is an EMF meter with a range of up to 20 milligauss.
The lights will light up based on the intensity of the
field, with red being a 20 or higher. It is operated by
holding one or both thumbs down on the switch in the
middle, though there are some modifications that use
objects such as a coin to hold it down and newer models
may come with an on/off switch. Some people claim it
can be used to "talk" to spirits. Typically this is
done in the form of yes/no questions by telling spirits
they can light up the lights once for no or twice for
yes. Your legacy lives on, Captain Pike.
ARG itself is unsure about this use. While they never
seem to want to "talk" to us, we have been in groups
with multiple K-II users getting individual answers to
questions. Statistically speaking, if someone were trying to
fake results by generating an electromagnetic field
through whatever means, it would be very difficult to
project such a small and precise field across entire
rooms as to only lighting up one meter.
One of these instances was in the 1st Class Pool on the
R.M.S. Queen Mary
in December, 2007. The room is very large and people
were spaced out on both floors and across the room from
others. A K-II session was being conducted to which one
person would seem to get an answer to one question, and
then shortly after someone across the room would get an
answer to another question. Interestingly enough, our
Sperry
never picked up anything above the background reading of
0.1, even when standing next to people getting results.
While we have found that is possible to silently
manipulate the thumb switch and cause the K-II to light
up, we know some of these people and do not believe they
would try to fake something like that. Statistically
speaking, eight people trying to fake K-II results over
the course of 30 minutes would overlap with one or more
other people many times, which was not the case.
Unfortunately, the frequency range on the K-II makes it
extremely susceptible to mobile phones and other
communication devices. It is very important to
keep such devices powered down during an investigation.
The K2 also seems to be a popular target for fraud due
to the visual element of its use. We suggest
looking into a radio frequency detector that will
display the frequency of the strongest source. We
use one and have had great success in detecting false
positives and fraudulent results. |
