NEW! From AlphaLab, Inc. makers of the original TriField Meter Model 100XE.

The TriField EMF Meter Model TF2 is an AC gaussmeter, AC electric field meter, and radio power density meter in a single unit, that combines all the features needed for fast, accurate measurements of electromagnetic fields (EMF). In addition to standard AC measurement modes, a special frequency weighted mode will properly scale the magnetic and electric measurements to indicate the full magnitude of currents produced by each type of field inside the human body. (If only powerline frequency is present, Standard and Weighted will read the same. If higher frequencies are present, Weighted reads higher). Made in USA by AlphaLab, Inc.

Magnetic (“MAG”) Fields– Turn the knob to Standard MAG or Weighted MAG. Read the large numerals in the center. In a typical home or office with low EMF, living areas will read 3.0 milligauss or less on Standard MAG and 5.0 milligauss or less on weighted. In a car (gas or electric), the reading may be higher. “Weighted” emphasizes the frequencies that are higher than powerline frequencies, while “Standard” measures all frequencies equally. Some home locations, such as near the breaker box, will have a higher magnetic field. If you rarely or never visit these high-field areas, the high reading is not important. The fields are only important in locations where you spend time.

The magnetic readings show the field at the location where the meter is held, and is independent of how you orient the meter. It is also independent of whether your hand is blocking the meter. However, the electric (“ELEC”) and RF detectors are different. These sensors read the field correctly when the top of the meter is pointed toward the source, but your hand CAN block these fields, so hold the meter by its lower half when measuring electric or RF.

Electric (“ELEC”) fields– In an electromagnetically quiet home or office, both Standard and Weighted will read less than 10 V/m, but the reading may be higher when the meter is pointed toward fluorescent lights, a wall outlet or switch plate, or an improperly-grounded appliance.

RF– Digital RF signals are pulsing. This means that the peak power density (see PEAK on the upper left of the screen) is higher than the average power density (main number in center) and you will see the bars pulse up and down if digital RF signals are present. THE MAIN (AVERAGE) NUMBER MAY BE FLUCTUATING. THIS IS A PROPERTY OF DIGITAL SIGNALS; IN THIS CASE, THE PEAK NUMBER IS MORE CONSISTENT. A “smart meter” from your electric power company only pulses about once a minute. To read this pulse strength, hold the TF2 near the “smart meter” and wait for the bars to jump. Then read the PEAK number, which will hold for several seconds. Smart Meters from the gas company pulse much less frequently (perhaps only once a day) so it is difficult to read RF from them, but they pulse so infrequently that it is probably irrelevant. Wi-Fi routers, that are broadcasting, pulse more than once a second. Computers (and other devices that are on line with a WiFi router) emit much less RF power than a router. Microwave ovens leak a significant amount of RF, but it is more continuous, not digital pulses. An RF quiet area will typically have less than 1.000 milliwatts per square meter as a peak (highest PEAK reading after watching the meter for a minute), and 0.200 average (the large numerals). RF can be effectively shielded by placing any metal sheet (aluminum foil or aluminum siding) or metal mesh (aluminum screen door material) between you and the RF source, which is typically a cell tower. Metal sheet or mesh affects RF in the same way that a mirror reflects light. Note that both RF and electric field are affected by where you stand or position your hands relative to the meter. These fields are usually stronger near the surface of your body because you are electrically conductive. If you hold the meter, it will read the field correctly in the vicinity of your hand. If you set the meter down, the reading will often be lower because the field is lower away from your hand. Inside an elevator, the RF and electric field are essentially zero. Unlike several other meters which have a false high reading in RF, the TF2 actually reads near zero in this environment. Near zero-field environment can also be achieved by wrapping the meter in aluminum foil (except for a small opening to see the display). This demonstrates how well foil will shield RF and electric field.


Older Discontinued Model remarks

We have used the Trifeild Meter for many years to test microwave ovens, electrical outlets, wall switches (especially the dimmer switches that leek), lamps (fluorescent are especially leaky).
When you are testing your sapper or hand holding rife I check to see that the machine is sending energy through.

Use the Trifeild Meter for testing

  • Appliances around your house
  • Test your zapper for success in your use of the zapper or rife machine

From the Manufacturer

  • Made in USA
  • Magnetic, Electric, and Radio/microwave Detection All in One Package
  • Omni-directional electric and magnetic sensitivity
  • Hand-held portability and simplicity
  • Extremely easy to use
  • Made in USA
  • 60Hz is for North America and 50Hz is for Europe

 

The TriField Meter is the only EMF meter which offers magnetic, electric, and radio/microwave detection in one package. This meter combines all these unique features with affordable pricing for fast, reliable measurements of electromagnetic pollution: Continuous sampling analog readout; Omni-directional electric and magnetic sensitivity; Two separate scales for magnetic field readings; Hand-held portability and simplicity. The TriField Meter will accurately measure EMF pollution from these “hot spots” in your home, office, or work environment so you can take steps for “prudent avoidance”: poorly grounded wiring, microwave oven doors, dimmer switches, strong analog RF transmitters, automobiles, TV's & computers, and other electronic equipment.

Please note: this product is intended to measure electric fields, and does not detect nuclear radiation.

Product Description

The Trifield Meter is a gaussmeter, electric field meter and radio field strength meter in a single unit. When measuring electromagnetic fields (EMFs), the primary concern is usually magnetic fields, which can be tricky to measure. If a less sophisticated 1-axis gaussmeter is used, a reading of zero could result even where the field is strong. A 1-axis meter must be oriented correctly to measure the field (which is a vector). The 3-axis Trifield Meter solves that problem by measuring the true strength of the field regardless of which way it is oriented. Therefore, the Trifield Meter can be scanned rapidly across an area without having to stop at each point to search for the orientation that gives a maximum reading. Another section of the meter detects AC electric fields, which can exist independently of AC magnetic field. The third section detects radio/microwave, such as from a leaky microwave oven. Analog (needle-type) display has very fast response time compared to digital. This meter is good for measuring AC (artificial) magnetic fields rapidly, AC electric fields rapidly, such as from overhead power lines or improperly grounded equipment. Can locate wiring in walls (using the 100XE version) and major RF/microwave sources such as leakage from microwave ovens, or the field near cell towers. Operates about 40 hours on replaceable standard 9V battery, has a low battery indicator.
