The Advantages and Features of the Trifield
EMF Detector
 |
•
The only meter which combines magnetic, electric and radio
/ microwave detectors in one handheld, compact, portable,
time saving, easy to use instrument, allowing fast &
accurate coverage of the entire nonionizing electromagnetic
spectrum!
• 3-Axis measurement (three dimensional) & detection
of electric and magnetic fields, which allows QUICK scanning
of offices, homes, hallways, power lines and vehicles,
etc.
• Independently measures / detects electric field
and magnetic fields and is properly scaled to indicate
the full magnitude of currents produced inside a conductive
body.
• Continuous sampling analog readout.
• Detects either frequency-weighted magnetic fields
(two separate scales) or frequency-weighted electric fields
in the ELF and VLF range. It has significant sensitivity
at 100,000 Hz, well past the 17,000 Hz horizontal scan
of video displays.
• Magnetic and Electric settings measure true magnitude,
feature usually only found on very expensive meters.
• Price range on this particular EMF Detector runs
from $129.00 to $159.00 depending where you buy it |
The
Specifications of the Tri Field EMF Detector:
 Magnetic - Scale: 0 to 100 mg (milligauss) - Minimum Sensitivity = 1
mg - Accuracy: + or - 20% - Frequency Range: 50 Hz to 100 kHz
Magnetic
Expanded Sensitivity - Scale: 0 to 3 mg - Minimum Sensitivity
= .2 mg - Accuracy: + or - 20% - Frequency Range: 50 Hz to 100
kHz
Electric - Scale: 0 to 1000 V / m (Volts per Meter) - Minimum
Sensitivity = 5 V / m - Accuracy: + or - 30% - Frequency Range:
50 Hz to 100 kHz
Radio
/ Microwave - Scale: 0 to 1 mw / cm2 (milliwatts per
centimeter squared) - Minimum Sensitivity = .01 mW/cm2 - Accuracy:
-50% or +100% due to reflections off the room and / or user
- 50 MHz to 3 GHz
Unidirectional
Switch Option - Available for an additional 35.00 -
Narrows the meter's three dimensional (3-axis) detection capability
down to single axis to isolate vertical magnitude sources.
Output
Jack / Analog Plug Option - Enables analog readout
capability - Allows interfacing the meter to voltmeters, computers,
or any device capable of interpreting an analog output. Maximum
voltage is approximately 300 mV and the output impedance is
10 KOHM - An Analog Digital Card (available at computer stores)
is a necessary item for meter / computer linkage via the output
jack - Available for an additional 9.50
Included
9-Volt battery allows 10 hours of total measurement
time. Alkaline battery allows approximately 50 hours of use.
ON
/ OFF Switch for LEDs - LED "backlighting"
can be switched on or off while meter is set to the ON position
- Available for an additional 9.50
Using the Tri Field EMF Detector
A knob on the front has six positions: OFF, BATTERY TEST, two
MAGNETIC field sensitivities (0.5-100 milligauss at 60 Hz, and
0.2-3 milligauss at 60 Hz, the second sensitivity to measure
weak fields more accurately), ELECTRIC field and RADIO/MICROWAVE
power density. The meter face is analog (needle type). A needle
reading of one-third of full scale corresponds to either 3 milligauss
(or 0.6 milligauss) @ 60 Hz, 3 kilovolts/meter @ 60 Hz, or 0.04
mW/cm2 respectively in the magnetic, electric, and radio/microwave
field settings. Average magnetic field strength in North American
homes and offices is 1-3 milligauss, so the meter is labeled
"HIGH" above these levels.
The electric and magnetic settings measure true magnitude, a
feature usually found only in more expensive meters. The device
is properly scaled to indicate the full magnitude of currents
produced by each type of field inside the human body. Depending
on the position of the knob, the meter detects either frequency-weighted
magnetic fields (two separate scales) or frequency-weighted
electric fields in the ELF and VLF range. The device has significant
sensitivity at 100,000 Hz, well past the 17,000 Hz horizontal
scan of video displays. The radio / microwave setting can detect
up to three billion Hz (3 Ghz), which lets you gauge radio-wave
power, CB and cellular phone equipment, as well as many types
of radar.
If you hold the meter in the center of a room and tip it to
various angles, the magnetic reading will stay approximately
the same regardless of which way you tip or rotate it. The electric
reading is similar, although the presence of your body alters
the actual electric field, so readings will vary more. The radio
/ microwave setting reads the full power of radio waves when
the meter is pointed toward the source. The magnetic section
of the Trifield meter has three field-detecting coils pointing
in the X, Y, and Z directions. A circuit amplifies these signals
and gives them the proper frequency weighting (sensitivity increase
linearly from 30 Hz to 500 Hz, with some residual sensitivity
up to 100 MHz). A unique network combines the three coil outputs
nonlinearly to approximate a true magnitude. The meter is sensitive
from 0.2 to 100 milligauss full scale at 60 Hz (or 0.1 to 50
milligauss full scale at 120 Hz, etc.) with a resolution of
0.2 milligauss in the sensitive range. Accuracy is + / - 20%
at mid-range.
