The radio/microwave detector is sensitive from 100,000 to 2.5 billion oscillations per second (100 KHz to 3 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.


The SUM setting in Model 1 adds together the electric and magnetic fields and detects if either field changes. Model 1 is used to find a disturbance in either type of field, but in the SUM setting it can generally detect if a person approaches to within five or ten feet, even on the other side of a wall. For this reason, Model 1 is preferred for parapsychological research, when, for example, a room to be measured is known to be vacant for an extended period (except for experimenters, who remain relatively still for that period). In Model 2, the SUM setting is magnetic plus radio/microwave (which requires somewhat more battery power to operate than the Model 1 SUM, but Model 2 also has an AC adapter). The SUM setting in Model 2 is for early warning of any unusual atmospheric electromagnetic activity, such as geomagnetic storms or ball lightning. In this setting, it does not falsely trigger when people walk by.

If you are an RF engineer or well versed in RF and meter specifications
please go ahead and browse the meters below.

Our prices reflect the lowest available-we will also match a legitimate price we have overlooked.

If you are not an engineer and are just looking for help with your sensitivity or to measure your environment. Here are some basic guidelines as there are thousands of meters and analyzers out there.
We carry these meters particular meters as they work!, and are the most cost effective in analyzing your environment so you can remediate as best as possible the RF and digital signal sources. We have an extremely EMF sensitive person that uses these tools and tests new ones regularly.

You need at least two meters or functions:

One for RF signals (ED78S, ED85EXS, Trifield, Acoustimeter)   
One for Magnetic (3 axis Milligauss, ED78S, or Trifield) measurement.


On the RF side- The Acoustimeter is a higher price point, yet is the easiest to operate for an amateur.  The reason for this is it has an excellent audio board and section that allows you to hear
signals and digital pulses.  You will also need a magnetic meter, the 3 axis milligauss meter being the most sensitive.


The Cornet meters are more economical, and also have a sound function, but the sound section is not as sensitive in the audio section as the Acoustimeter. The Cornet RF measurement sections do work very well with the digital numbers on the display to measure the signals.
The ED85EXS meter does not have magnetic (gauss) but does have a wider frequency range of measurement and the ability to change antennas.  You will also need a Magnetic function meter- either the 3 axis milligauss or the Trifield meter.
The ED78S meter is kind of a cross breed that does have the RF and Magnetic (Gauss) function into one meter. If you want to order only one meter. 


The Trifield meter falls into this dual function category also, however it does not use a digital display it uses an analog needle display, and also no audio function. 

Examples of:
RF sources:  Cell towers, microwaves, Smartmeter, WiFi, wireless phones, etc...

Magnetic (gauss) Sources: AC Power Line interference, local Transformers, Motors, & Appliance EMF.

3 Axis Milligauss Meter

Excellent readings for magnetic fields.

This meter measures AC magnetic field in a wide frequency range of 13 Hz to 75 kHz (75,000 Hz). The frequencies include most ELF (that is, frequencies below 1 kHz) and VLF (above 1 kHz) magnetic fields. The meter measures the true 3-axis magnitude of the AC field. Two other more specialized measurements can also be performed: 3-axis VLF-only (1kHz – 75 kHz) to measure the strength of higher-frequency fields, and 1-axis full bandwidth (13 Hz – 75 kHz) to determine the principal direction of the AC magnetic field.Most measurements will be performed with the knob turned to 3-Axis ELF+VLF. This setting is for measurement of true magnitude of magnetic field at the widest range of frequencies (ELF + VLF).

The SLEEP Tone Generator utilizes the same principles and technology as the RELAX Earth Tone Generator. However, the SLEEP frequency is calibrated to 4.0 cycles per second, a frequency associated with the delta range of brain activity - deep, restful sleep.

A soothing hum below the range of typical human hearing, the SLEEP Tone allows many users to settle down more easily with less mental chatter and fretting. Then prepare to wake up refreshed and well-rested after a night with less tossing, turning and waking up in the middle of the night.

Intended for use in the home, office or auto, this device features a larger signal coil and comes equipped with two power supplies: a 110 volt power supply for the home and a 12 volt power adapter for use in the car, truck or camper. Each unit is design to impact approximately 10 feet (3 meters) in any direction, with greatest effect nearest the unit. Size: 5.0" x 5.5"x 1.8" (127mm x 140mm x 46mm).

How can the RELAX and SLEEP Tones be beneficial if they are below the range of human hearing?

What we call "sounds" are actually mechanical vibrations that can travel through air, liquids or solids and that are recognized by the human ear drum. While vibrations moving below around 20 cycles per second (hertz) are not heard by the ears of the average person. For this reason, The Tone Generators use a dual-spin coil antenna to create a low level energetic field to directly stimulate the body's natural electrical/energetic field.

Just as musical tuning forks resonate when exposed to harmonic frequencies, the human body can sense and resonate in response to those tones below 20 cycles per second. This is especially true since four out of five of the normal activity levels of the human brain have been measured to be within these sub-audible ranges of vibration:

The average person will perceive the low frequency Tone as a soothing hum, or perhaps not at all. But the body and brain will recognize these tones and, through the principle of entrainment, will often seek to find a state of resonance with the external tone. In this way, the brain may pleasantly and easily fall into rhythm with the Tone, producing a comfortable shift in mood and state in the process.

A meter that detects small changes in natural DC fields and some radio transients.

The TriField Natural EM Meter was designed to do field measurements for special research. It detects changes in extremely weak static (DC or "natural") electric and magnetic fields, and 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. Because 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 AC fields. Normal construction materials don't block magnetic fields, so the meter can be placed indoors and will work equally well, and due to the built-in tone, it can be used in the dark, and will sound the tone at whatever level of field the user sets. Model 1 operates on a standard 9-volt battery, and Model 2 runs on a 9-volt battery or an AC adapter (both included). Model 2 has an input jack for an optional high-sensitivity magnetic coil. Both models are covered by a one-year warranty.


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. Model 2 is sensitive down to 0.05% of the Earth's magnetic field when the optional external coil is used. After the meter detects an event, when 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 will remain at rest until the field changes again. The threshold level (squelch level) of the tone is adjustable. The user determines the amount of change in the magnetic field 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 larger, the tone's pitch will be higher. This meter can also be used to determine if anything is magnetized. For example, if a bed frame is magnetized, the meter can be held vertically and slowly be swept by hand over the bed. Any changes in the direction or strength of the magnetic field will register. A similar process can reveal the presence of magnetic rocks just below the ground.

The Natural EM Meter 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 thunderstorms. It will signal the movement of any distant, strong magnetic sources in the sky, even if the sky is cloudy or the source dips behind a hill. Ball lightning should in theory be associated with a strong magnetic field, and magnetization of metal on the ground has been reported with some sightings of unusual lights in the sky.


When the dial is set to ELECTRIC, the meter is sensitive to electric fields as weak as 3 V/m (volts per meter). 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". A 3V/m field is so feeble that if a 10'x10'x10' room were filled with a field of this strength, it would contain the total amount of energy equivalent to that required to lift a single grain of table salt 1/50th of an inch.

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), its sensitivity is of interest to researchers in the field of parapsychology. 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.

What is Schumann Earth Resonance?

Just as musical tuning forks resonate when exposed to harmonic frequencies, the naturally-occurring electromagnetic and atmospheric activity of our planet resonates in harmony with a family of frequencies that are defined by the distance between the Earth’s surface and the ionosphere - the conducting plasma layer of the atmosphere that stretches from 40 miles to 950 miles above the ground. These Earth resonance frequencies range from 7.83 to 59.9 cycles per second (hertz).

The were first documented observations of global electromagnetic resonance were recorded by Nikola Tesla in 1899. They were first predicted mathematically by the German physicist W. O. Schumann in 1952, then located experimentally by Professor Schumann and a colleague in 1954. For his contribution, the Earth Resonances were named for Professor Schumann.

The Earth Resonance Frequencies have been present throughout the history of the world. It should be no surprise that this planetary hum would have a special relationship with the life forms that live upon it.

Trifield ® Meter measures all three types of electromagnetic field: AC magnetic field, AC electric field, and radio (including microwaves). The magnetic and electric detectors are 3-axis, making the meter easier to use than comparable 1-axis meter
*The Radio/Microwave section of this meter reads most modern radio sources (50 MHz - 3 GHz).

Product Description:
The Trifield ® Meter is a gaussmeter, electric field meter, 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.


  • Detects the three types 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 far from civilization), while measuring up to very strong AC fields.
  • Electric range covers 5-1000 V/m
  • 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.


  • Measures AC (artificial) magnetic fields rapidly. (Does not measure DC of static fields, such as the Earth Field. Click here for other magnetic meters).
  • Measures AC electric fields rapidly, such as from overhead power lines or improperly grounded equipment. Can locate wiring in walls (using the 100XE version).
  • Measures 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 if very near the source.)
