Product Description

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.

From the Manufacturer

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.

As a former engineer, I was hesitant to buy this meter because of its relatively low price, and I almost purchased the higher priced Trifield made by the same company that has wider ranges of frequencies of the different fields covered. But some wise consultants at a company called LessEMF talked me into this one and a separate RF meter. I bought this one from Amazon because it was about $25 cheaper, and I bought the RF meter from LessEMF since it was not available from Amazon. The service and integrity of both companies are superb, and so are the products. This meter has been everything we needed to try to help my beloved wife with her Electromagnetic Hypersensitivity (EHS). You can measure both AC electric and magnetic fields in a wide range of strengths, and you can measure RF radiation from a microwave. But you CANNOT measure RF from other common devices like wireless devices (phones, computer routers, mice and keyboards, baby monitors, etc.). For those, you need a specialty RF meter.

My wife's EHS has virtually derailed our lives for the last three months, and I honestly do not know what we would do without this meter at this point. With it, we can detect problem areas in our own home and in the public places she frequents. So far, we have discovered we needed to eliminate all compact fluorescent bulbs even though I love the quality of light they produce. We have replaced them with bulb-shaped halogens that emit very low magnetic and electric fields. We determined that the microwave and oven had to be either unplugged or switched off at the breaker panel to keep the magnetic fields low enough in the kitchen for her to be safe. Simply having them off was not enough.

How often do you buy a product that changes what you do?

I became aware of EMF problems because of a friend who has power lines just outside her condo. After considerable research, I bought the TriField meter as the best product for the money. BTW I found that it's slightly cheaper plus free shipping if you make an offer on eBay to buy it. This product is great! Clear directions, and measures all the stuff that's important.

Here's what I'm now doing differently:
1. I rearranged our TVs so the older high-radiation sets are in rooms we don't use very often.
2. I sit on the other side of the dining table when the living room TV is on (it radiates like fury in all directions, out to 6 feet distance).
3. I try to stay 6 feet away from the microwave oven when it's on (you would be amazed at the field strength it produces).
4. Whenever possible, I set my cell phone (iPhone) a foot away instead of in my pocket next to my body - every time it "checks in" with the nearest cell tower, there's a spike in RF radiation nearby.
5. I am aware that wherever there's a running motor, there will be fields in the immediate vicinity - up to a foot away. So don't lean against a running dishwasher, for example.

I highly recommend this product!

What I liked about this meter:

- The fact that its like three meters in one, you can so easily measure, electrical, magnetic and RF radiation
- The price, especially from Amazon, which is difficult to beat

What I liked less:

- It's a bit unfair to compare really but I have a dedicated RF meter which is far more sensitive to RF radiation and I have a separate electrical and magnetic EMF meter which also gives more accurate readings. But each of these meters individually cost more than the Trifield 100XE, so this meter really is outstanding value for money.

What is the Trifield 100XE capable of?

- Identifying the general level of electrosmog in your environment
- Measuring the EMFs in your household wiring
- Identifying hotspots in your home. You might have things under control in your own living space but if your neighbor has their microwave oven behind your bedroom wall, the Trifield XE100 is going to tell you
- Many of the new video game consoles, Nintendo Wii, Xbox360 have transformers on them that generate EMFs, you can now measure your exposure.

I know that for many people the first time they use this meter it's like a revelation. They suddenly become aware of the EMFs they are exposing themselves to. My revelation came years before I bought this meter. Unlike most people I do not need a meter to tell me when there are electromagnetic fields in my environment; my head already does this for me.

I have been electrically sensitive since 2002. In the length of time it took to have a cell phone conversation I went from being very normal to being very electrosensitive.

I recently purchased one of the TriField EMF meters. I am a realtor and I had a client concerned about EMF from nearby power lines, so I decided to do my own test. Everyone has heard about the possible health threat from EMF. Any reading above 3 is not suppose to be exposed to for long periods of time. I checked with the power company and they stated the power lines were 12Kv which is low compared to high voltage transmission lines on towers. Wow, was I shocked and amazed. By the house and below the lines the readings were 15-20. I backed down the street away from the lines and I experienced high levels of exposure pass the second house on the block. We also recently purchased a massage bed and usually laid on it for 30 minute sessions. This too had extremely high EMF readings in the 20+ range. Forget about paranormal and ghost detection. Everyone should have one of these meters to see what they are being exposed to daily. With such high occurances of cancer and other diseases, I am going to do everything possible to protect myself, my family and inform the public of the possible dangers of EMF. If you do not already have a meter like this, buy one. I feel it is very important to your health and well being.
