Technology Alternatives 7021 Cell Sensor EMF Detection Meter

by Technology Alternatives Corporation

Product Description

From the Manufacturer

Recently, many studies have delivered warnings about long-term exposure to cell phone radiation and certain electromagnetic fields. But since these dangers can’t be seen by the naked eye, how can you protect yourself and your family? The CellSensor EMF Detection Meter measures both of these hazards with an easy-to-read gauge that also beeps and glows when high readings are detected. The CellSensor runs on one 9-volt alkaline battery (sold separately).

Please note: this product is intended to measure electric fields, and does not detect nuclear radiation.

Product Description

You might not know it, but certain areas in your home and work have powerful electro magnetic fields (EMFs) that can inflict severe damage to cellular DNA. Protect yourself against this invisible radiation by testing areas that you frequent with a gauss meter, a device that measures the strength of EMFs. Once you identify where EMF radiation hotspots are, simply avoid these areas. The accuracy of a gauss meter is easy to test. Just turn on your gauss meter and progressively walk towards a television set or any operating electrical device. You will see an immediate and consistent increase in the EMF measurement as you get closer to electrical devices, electrical wiring hotspots, and other surprising areas of your environment. Many people are unknowingly surrounded by powerful EMFs while they sleep. Their bed might be too close to an electric alarm clock, or they could be hit with EMFs that pass through the wall from a television set in the adjoining room. The solution is as easy as moving the alarm clock six inches further away from your head, or rearranging your bedroom furniture. A gauss meter often reveals surprises, such as the high EMF emissions from electric toothbrushes, shavers, microwave ovens, photocopy machines, cordless phones, and high-intensity electrical wiring. Once you know where the EMF hotspots are, just stay at a safe distance when the appliances are on. When using a regular corded or cordless phone, be sure to use the speakerphone option to avoid unnecessary exposure to EMFs. The Cell SensorTM is a handheld gauss meter that instantly measures EMFs from all sources. The Cell SensorTM is the only gauss meter on the market that can measure both cell phone radiation and electromagnetic fields (EMFs).

5.0 out of 5 stars EMF Radiation Detector, November 14, 2007

The Cellsensor was easy to use and helped find "hot spots" (where there is too much EMF radiation) and rearrange bed or furniture so we're not exposed to the hotspots.

Most culprits: Refrigerators, stoves, light dimmers, any kind of transformer/power adapter, outdoor power lines, fuse box. I don't think I need something more sophisticated for home use.

Home Contractors should have this.

Beware: An wall may show no EMF until the wires behind it carry a load (something is plugged into a socket that uses electricity).

This review is from: Technology Alternatives 7021 Cell Sensor EMF Detection Meter (Tools & Home Improvement)

I bought this device to detect the radiation at my home, but despite it being named "cell sensor", I was unable to detect the cell phone signal from my iPhone 3G. I followed the direction, did the 90 degrees and 8 inch apart as described in the manual, put the probe next to the sensor, put it on the sensitive setting, and... detected nothing. Then during a call, I tried moving the cell phone in all angle combinations... nothing. I thought I had a defective unit, so I requested a replacement, got another brand new unit, and did the exact same thing. Nothing... the needle stays around 0. Same goes with wireless mouse and baby monitors. How do you make a "cell sensor" that doesn't sense a cell phone is beyond me.

On the other hand, this device works well detecting EMF from appliances such as refrigerator, microwave, lights, etc. Not sure it has really helped me avoid EMF energy other than confirm there's EMF emitting from electronic devices, and to stay 6 feet away from the microwave, but otherwise the level is so low typically that there's really not much that needed to be addressed.

If you plan to get this to detect EMF, it seems to work well, although I have nothing to compare it against. On the other hand, if you want to get one to detect wireless radiation, forget it.

4.0 out of 5 stars no need to buy high price EMF meters, August 4, 2007

Works great! Push button on and go, it'll light up when EMF is detected letting you know without even looking at it, and the two modes (normal or high) are great if you need more precise or more broad of a reading, normal read 0 to 50 milligauss, and high reads 0 to 5. I haven't used the EML mode much so I won't rate that, but it does work. Plus the probe is seperate so you can move it around to get a tri-field effect for better readings. The only reason I didn't give it a full 5 rating is that I don't think the range is very good, I think three, maybe four feet is the maximum range, but that's good enough for me.
