This is the only version Alphalab and Geovital recommend for measurements related to health as this is the 'weighted' version, not a 'flat' measurement. If you insist on a 'flat' measurement we have that version available also. Please contact us.

Is your home free of radiation

The original TriField ® Meter combines all the features needed for fast, accurate measurements of electromagnetic fields. It independently measures electric field and magnetic field, and is properly scaled to indicate the full magnitude of currents produced by each type of field inside a conductive body. As a result, it "sees" much more than any other electromagnetic pollution meter.


NOW WITH FREE GEOVITAL ACADEMY TRIFIELD METER USER GUIDE

The original instruction manual that come with the Trifield meter is a little small and more technical than anything else. Geovital Academy, who train people in making professional assessments of properties, have developed a small Trifield Meter user guide with hands on tips and ticks on how to use the Trifield meter, what to measure and look out for, what levels to be aware of etc etc. It is easy to operate the Trifield meter, but with this user guide you will also have confedence that you are using it correctly. When you purchase your Trifield meter from us it is included FREE OF CHARGE.


Depending on where the knob is set, the meter 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. 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, and many types of radars.


This meter is the only one which combines magnetic, electric, and radio/microwave detectors in one package, so that the entire nonionizing electromagnetic spectrum is covered. In addition, the magnetic setting and the electric setting measure true magnitude, a feature found elsewhere only in more expensive meters. 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 radiowaves when the meter is pointed toward the source.


Surprisingly, the standard TriField Meter is one of the least expensive meters available. The few other meters below $300 read only low-frequency magnetic fields and only in one direction (not true magnitude). 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 increases linearly from 30 Hz to 500 Hz, but with some residual sensitivity up to 100 kHz). 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. A version with flat frequency response (instead of linear sensitivity increase) is also available for the same price.


The TriField Meter comes with a 9-volt transistor battery included. This type of battery lasts about 10 hours (total measurement time). When the BATTERY TEST reads low, the battery can be replaced with any rectangular 9 volt transistor or alkaline (which lasts about 50 hours) type. This meter is manufactured in the USA. TriField is a registered trademark of W.B. Lee.


Features:


- Detects the three type of electromagnetic pollution: AC magnetic fields, AC electric fields, and radio/microwaves.

- AC magnetic and electric fields are 3-axis, allowing quick accurate readings regardless of meter orientation.

- Two magnetic ranges cover 0.2-100 milligauss.

- This is sufficiently sensitive to detect the background field almost anywhere (except for from civilization), while measuring up to very strong AC fields.

- Electric range covers 5-1000 V/m (or .5-100 kV/m with original version of the Trifield Meter)

- Radio/microwave covers 10 to 1000 microwatts/square cm which includes the maximum permissible public exposure levels in all countries.

- Operates about 40 hours on replaceable standard 9V battery, has a low battery indicator.

- Analog (needle-type) display has very fast response time compared to digital.


Applications:


- Measures AC (artificial) magnetic fields rapidly. (Does not measure DC of static fields, such as the Earth Field.)

- Measures AC electric fields rapidly, such as from overhead power lines or improperly grounded equipment. Can locate wiring in walls (using the 100XE version).

- Measure major RF/microwave sources such as leakage from microwave ovens, or the field near cell towers. (Note that wireless internet transmitters and individual cell phone are designed to emit very little power and usually are well below international RF exposure threshold. Consequently, the Trifield Meter will only detect these it very near the source.)

Using The Trifield Meter


A knob on the front has six positions: OFF, BATTERY TEST, two MAGNETIC field sensitivities (0.5-100 milligauss at 50 Hz, and 0.2-3 milligauss at 50 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) @ 50 Hz, 3 kilovolts/meter @ 50 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 labelled "HIGH" above these levels.


Magnetic Field Detection


In most homes or offices, some areas are "hot" spots with readings in the HIGH range. Most often, this is caused by magnetic fields, which come largely from unpaired internal wiring. (Contrary to popular belief, power transmission lines and transformers do not generally contribute as much magnetic field as does internal wiring.) Other magnetic sources include video displays, motorized clocks and other equipment, electric blankets and heaters, fluorescent lights and light dimmers, and the transformers that are inside consumer devices. Much of the total field strength is from frequencies that are harmonics or multiples of 50 Hz (100 Hz, 200 Hz, etc.) and 17,000 Hz of video displays. Cars (especially near the front floorboard of electronic ignition cars) and motorcycles have fairly strong fields that are at frequencies higher than 50 Hz. Magnetic field is difficult to shield, but sheet steel is somewhat effective.


Electric Field Detection


A few areas in most homes read HIGH in the electric field setting. These include areas near improperly grounded equipment, the front of video screens, and fluorescent lights. Most of these fields can be easily shielded using a grounded metal screen or foil; VDT screens of this type are readily available. You can greatly reduce the strength of an electric field just by placing your hand in front of the source. This effect can be seen using a TriField meter.


Microwave Detection


Occasionally, certain areas read HIGH in the radio/microwave setting. These include door seals around microwave ovens, and cellular phones (but not regular radio phones, which are very low-power). Radio/microwaves can be shielded in the same way as electric fields, although the lower frequency radio waves are not shielded by your hand as easily as microwaves are. (Metal screens will shield both.) In the United States, radars and FM transmitters can legally expose residents to moderately high power levels (as high as 10 mW/cm2 briefly or .57 mW/cm2 near cellular towers), but such exposure is not common.

Reducing Field Exposure


By seeing "hot" spots in your home and office, you can move equipment or furniture to reduce exposure. If a room has a "hot" spot, fields are generally much weaker elsewhere in that same room.
