Tools and Hardware Reviews of Technology Alternatives 7021 Cell Sensor EMF Detection Meter
Customer Review: Good for EMF, not so good for radio/cell phone detection
Summary: 3 Stars
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.
Customer Review: Good product
Summary: 5 Stars
I like this device very much, it looks and feels like it was very well designed and manufactured - it surprised me with high readings at the small fan that was near my head (no longer), and at the front of an old toaster oven (which has been taken to a toxic waste site, along with the fan.) The only questions I have are, how do we calibrate it, and why can't you prepare it for shipping, with less wrapping?

We're starting our house hunting recently. We found this meter from Amazon and received it two days after online order. So good service. It's nice to have this meter in your pocket and measure how a house is affected by electric lines over it. We also use it at home for computers, microwave, cell phones... The meter works very well. Great to know that our family is living in a safe and green environment!Customer Review: Great Meter for Ghost Hunting!!!!!!
Summary: 5 Stars
THE GHOST METER! This EMF is very simple to use and is perfect for Ghost Hunting and finding hot spots in your home. I mostly use it to detect paranormal activity. It is compact, lightweight, acurate & comes with probe to fit in hard to get areas. You can adjust the detection volume all the way down to be silent or as loud as you want. Has a red blinking light that goes off when activity is present, and is great for in seeing the dark. The higher the EMF reading, the faster the red light blinks. This unit takes one 9 volt battery. This meter is one of the most suggested EMF's by paranormal investagators/ websites. Don't leave home without this EMF GHOST METER!!!!!!!Customer Review: Great little EMF meter for the price of $30.
Summary: 4 Stars
Great little EMF meter for the price of [...]. I decided to purchase this EMF meter after inquiring about a many more digital EMF meters and when I got this one I was pleasantly surprised it works well. It has sensitive setting of 1-5 mlGauss and then a normal setting of 10-50 mlGauss for typically higher level EMFs. The sensor is on a dongle connected to the meter and I've put a 3M velcro sticker to attach it to body pointing forward and able to remove it if needed.
I purchased this through Spectral Technologies on Amazon.com . It was incredibly fast shipping and the item arrived as described with tracking and no one can beat their price even with shipping costs. I put a 4 out 5 for them but they really deserve a 5 out of 5 so I removed my rating of them.
