EMF Meters

You might be surprised where some EMF “hot spots” are located in your home and office.  Like possibly where you lay your head for 8 hours at night due to the 60 Hz alternating current within the electrical wiring in the wall behind your bed or the 2.4 GHz wireless router on the other side of a wall or the nearby cell tower that’s disguised to look like a tree.  We're also increasingly exposed to high frequency voltage transients, also known as "dirty electricity".  All the different types of EMFs have been linked to multiple health issues including cancer, neurological disorders, chronic fatigue, headaches, etc.

 

 

Sometimes the solution to an EMF related problem is to simply move something, e.g., moving a child's bed

or moving an appliance from one wall to another.  The first step is to know where the "hot spots" are.  If you're located in the Southeastern US, Indoor Environmental Solutions can perform an EMF survey, which includes measurements of various frequencies and sources of EMFs and recommendations for resolving any issues. If you would prefer to perform a survey yourself, you should measure magnetic fields from Extremely Low Frequency (ELF) EMFs with a Gauss meter, measure Radio Frequency (RF) radiation with an RF meter and measure high frequency voltage transients or "dirty electricity" with a Graham Stetzer meter.

 

Children are even more at risk, due to their thinner skulls and their developing brains and neurological systems.  EMFs have been linked to increased risk of leukemia, brain cancer, possibly ADD, autism, etc.

 

 

When it comes to cancer and many other diseases,

an ounce of prevention is worth infinite pounds of cure.

Too often, there is no cure.

 

Measure Extremely Low Frequency (ELF) EMFs With

 

GAUSS MASTER™

Also known as "Dr. Gauss"

 

 

This little meter measures the level of ELF magnetic field radiation from power lines, computers, kitchen appliances, and more! The easy to read scale, unique built-in audio signal and auto shut-off make it simple to use and a great way to find hidden sources of ELF frequency magnetic fields.

 

Most experts agree that chronic exposure to more than 2.5 milli-Gauss is inadvisable. This meter will show you which areas are above or below 2.5 milli-Gauss in the 50 - 60 Hz frequency range.

 

Hand-held, lightweight and durable, with two easy to read scales (0-1 mG, & 0-10 mG), and dramatic audio signal. Our favorite meter for demonstrating the presence of dangerous EMFs to others and paranormal work. Requires one 9V battery (not included). Calibrated at 50-60 Hz.

Includes nice instructions on how to perform a proper survey of your home, office, or school yard.

STETZERiZER Microsurge Meters

 

Designed to measure home and office Power Quality,

"Dirty Electricity", aka High Frequency Voltage Transients

 

 

The intellectual property behind the Microsurge meter belongs to the individual

who conceived and designed the meter: Professor Martin Graham.

 

The Microsurge meter:

 

 

    LCD display reads the Volts per second present, which is an approximation for the high frequency energy. High frequencies are the frequencies which are most harmful to equipment, animals, and humans.

    The good, marginal, and undesirable range of meter readings are conveniently listed on the back of the Microsurge meter.

 

Electrosensitive people have reported sensitivities with readings as low as 27 on the Microsurge meter. However, medium or even low Microsurge meter readings should not be interpreted as a guarantee that there is no harmful health impact; only a medical expert can determine that. Caution is required. Some harmful health effects of high frequency energy on humans appear to be cumulative, and possibly non-reversible. Science is inconclusive in this area, although the body of empirical evidence available for guidance continues to expand and stabilize.

Technical Information

 

The GS Microsurge Meter measures the current in a 800 picofarad capacitor connected across the terminals of the outlet into which it is plugged. One GS unit is .02 micro amperes. A meter reading of 50 would indicate a current of one microampere. A human having a low impedance to one of the terminals of the outlet (the grounded wire) and a capacitive coupling of 800 picofarads to wiring connected to the other terminal of the outlet (the hot wire) would have a current flowing through them indicated by the GS Microsurge Meter. The capacitance of two parallel metal plates that are one meter by one meter and separated by one centimeter is about 800 picofarads. The capacitance of a human to the hot wires will usually be less than 800 picofarads and the current through the human will be proportionatly lower. The current flow through the human will also depend on how the capacitance of the human to the wire is distributed over the human. This is important since it is the current flowing inside the body and where it is flowing that determines the effect it will have on the human. The frequency band covered by the GS Microsurge Meter is about 10 kHz to 100 kHz.

 

Microsurge Meter Design Criteria

Microsurge meters were specifically deigned as a companion to the STETZERiZER filters. The meters measure the level of harmful electromagnetic "energy" present, and their primary use is to guide effective filter installation.

 

Microsurge meters are low cost, robust, and easy to use by non-technical people. The meters were designed to measure harmonics and other high frequency "energy" present, which are the frequencies most detrimental to human health. The meters effectively ignore the effects of 60 Hz power and other lower, less harmful frequencies. Specifically, the meter measures the average magnitude of the changing voltage as a function of time (dV/dt), which naturally emphasizes transients and other high frequency phenomena that change rapidly with time. The measurements of dV/dt read by the meter are defined as G-S (Graham-Stetzer) units (since no standard term is available). The G-S units are a measure of "harmful energy" which is a function of frequency, or more generally, rate of change of voltage or dV/dt.

Using the Microsurge Meter for a Typical Home Installation

 

Microsurge meters measure the levels of safe, borderline, or dangerous levels of "energy" present. These levels are conveniently shown on the back of the meter for reference. These levels have been developed through research (much of it in Russia and neighboring countries) and confirmed by experience in North America. The levels have been adopted by the Sanitory Stations (Health Departments) of the Republic of Kazakhstan.

 

Starting from points that typically have the highest readings such as the power input panel, computers, and televisions, the meter is used to measure the initial levels of G-S energy and reduction as filters are added. Once the G-S levels are acceptable at one location, the process should be repeated at the next location. After the installation of the filters is complete, a final confirmation of the G-S levels should be performed throughout the house.

 

Works for 60 Hz/120 Volt North American and 50 Hz/240 A.C. Volt European systems
