Magnetic Field Meter

This Product is no longer available.

A reliable Peak Hold and Data Logging Magnetic Field Meter, at a reasonable price.  Set it in your bedroom tonight and find out in the morning if there were any magnetic field fluctuations from the nearby power-lines overnight while you slept.  Or use it in any room where you are concerned about magnetic field exposure levels.

This magnetic field meter is one that we use in our EMF Consultant Certification Course for those students that have some experience with metering.. It is a good upgrade to add to your growing meter collection of EMF Meters since it offers more features, like Peak Hold and  Data Logging than the TriField Meter that we recommend to our beginner students for its ease of use and lower price point.

It's sold under various names (white labels) that offers good metering features that most EMF safety minded consumers are looking for when evaluating the magnetic field exposure in their homes.

Here are the specs for the parent meter: TENMARS 192D. It is not what I would call a “professional” meter in the strict sense of the word, more of a good basic meter for measuring residences, offices and places where strict compliance with regulated standards are necessary.

We offer it here at a low student price of $195, for the convenience of our students, to avoid the confusion between various brand names it is sold under, to help locate  the recommended model exactly, and to enable buyers to obtain the manufacturer's User Guide with valid Manufacturer's Warranty Material.

Why Do You Need a Magnetic Field Meter?

Numerous  health studies have shown that safety precautions should be taken to safeguard from high exposure of magnetic fields from electrical wiring, electric appliances etc.,  in places including medical institutions, schools and residential districts, where people spend extended periods of time.   In particular, measuring  your magnetic field exposure with this type of meter enables you to knowledgeably evaluate your risk, and put in place protective measures to safeguard those especially at risk, such as patients, babies and senior citizens from exposure to high electromagnetic waves.

What is a Magnetic Field Anyway?

A magnetic field is a field of energy caused by electromagnetic waves, which simply means the wave motion of the electromagnetic field (EMF). The change in electric fields produces magnetic fields, and the change in magnetic fields can also generate electric fields. The fluctuation of correlation between each other is known as “electromagnetic waves”, which is a form of EMF energy. Light and heat are two examples of EMF, but unlike these two familiar and perceivable forms, there are many more forms of man-made EMF that our bodies have not evolved to co-exist with, and so we cannot perceive them without the aid of an EMF detection meter.. 

Man-made EMF is produced by the electrical wiring in your home, your various electrical appliances and much more. Electromagnetic waves  can be transmitted either by radiation in the air or by an electric conductor. So, as initial protective measures we recommend  strategies that involve creating distance between you and the EMF source, such as limiting time near it, rearranging furniture to avoid it, etc. in the locations in your home and work  where electromagnetic fields are detected the strongest in order to avoid prolonged exposure to excessive electromagnetic fields, of which magnetic fields are a part..

"Awesome certification training!  I hit the ground running (with confidence) the day I finished the course, and my business has been built from the ground up based on the tried and true methods of a true EMF Professional that would have been far beyond me without this training."
   Ross Chambers, Toronto, Canada

"Electrosmog can be more dangerous to you than you think. I was electronically stalked by a cellphone hacker, Chris returned my SOS message within the hour and walked me step by step through how to protect myself right away. I went on to take his excellent training to learn how to protect myself from the many other risks of electronic pollution - I never realized how insidious EMF is!"
          Theresa, San Diego, CA

The Bedroom Sanctuary ebook guided me through everything I needed to know to finally eliminate and block the various sources of EMF in my bedroom causing my sleep disorders. Ah, to sleep perchance to dream - blissfully at last."
                  Chas Chavez, Texas

"This Certification Training is simply the best there is. I thought I would learn how to wave an EMF meter around and that training would be very American based, and instead I learned more professionally valuable, global-in-scope, and life-saving info than I ever imagined. I say 'life saving' because my wife, who took the training with me,  is convinced this training saved her life. Three words of advice: Take this training!"
