Cell Sensor EMF Detection Meter

This is sort of "lacking in real quality" but what do you expect for $25? So, the fact that it works, though you do it with no real idea of any sort of accuracy of any kind, and it does the basic function, that of telling you "Hey, you have a lot of leakage power here!" --- it does that well. Example: I took it down to my newer GE over-the-stove micro wave oven. From the very front, it was not too bad, but from the sides, and top/bottom, it went ballistic and set off the lights and buzzer. TI'm afraid that this is sort of typical from all of society and electronics manufacturers. (A lot of money rides on this stuff!) On my older later 1980's vintage Ammana Radar Range? Almost zero leakage and detectable output. Our standards are so lax these later years that almost anything goes and THAT is probably not good for our bodies. No radiation in general is good for you when it is large enough that it causes currents to flow through you on a cellular level inside you body...... it is a cumulative thing - and some folks are MUCH more suseptable to it than others so the people who set the standard are hard put to set a point of safety: safe for me may be unsafe for you. Think of this: after 15 or 20 years of such high levels of exposure..... what shape will you be in? The associations have not been PROVEN yet because it takes so much time, but cancer and tumors are the primary concerns, in general, right now...... the big Questions are, "How much is too much and for how long?" No one absolutely knows this yet. (It could a bit like, "We always suspected that cancer & cigaretts went together!") We all know already that cell phones output a LOT of radiation..... the further from the cell tower you are located when you talk, the higher the cell outputs it's signal strength to get the connection working well, and.... the greater the risk to your body and brain cells. We all already KNOW this fact, we do NOT NEED a meter to tell us this as new information..... and this device will not really give you a real good idea of how much you are getting exactly anyway. However, what it will do, is that it will tell you when you need to get further away from some radiating appliance, phone, TV, microwave oven, or such.... to some degree anyway. What makes this a good deal? As opposed to spending 5 times as much (or more) for a "Tri-Meter" is that it gives you a general idea with more ability to tell one level from another. It does not cost you $150 to find out what you already knew intuitively anyway. (humor intended here) If you want real quality, do not mind paying for a higher level of precision and accuracy, you can do as I did and buy something like the ExTech 480836...... aaaand you will spend basically $250 too. It is NICE! Has some real good quality in it equal to many of the good quality multi-meters you can get, and it is also tri-mode ops which is a plus compared to a single mode like this one. So, I use this to give rough estimates in ultra-low frequency applications only, and it has a rather short close range limited ability too. But for $25 what more could you ask for? The small probe is a nice conventient added plus for it as well. Enjoy!

I give this device four stars based on the following: - easy to use - identifies EMF levels accurately and consistently - has both audible and visual alerting - very good documentation After locating and identifying the hot spots in my home I was able to make the adjustments to my furniture placement to limit my exposure to harmful EMF. I also researched and purchased excellent EMF blocking fabric fromI'm a type B person and it took me the longest time to decide to try this "toy" looking device. Save your money on buying those cool 3-axis more costly models if you don't need to. The cell sensor works great! By the way, if your cell phone doesn't make the thing go off, then you've got a good phone! I tested three cell phones and only one set it off!

Highly recommended EMF Meter. Simple to use and works great at recognizing problem spots. Microwaves give off EMF's even when off, it's a good thing to stay 5 feet away from them. I was able to fix an EMF source around my computer. The EMF's were coming from the wires near my feet. So I plugged a power adapter further away on another plug and that fixed that problem. I would have never known about that EMF problem. I like the way this unit beeps and flashes a light when the EMF is too high. The power button looks very sturdy, the unit is light weight but this is a good thing. If you need an EMF meter that is easy to use and low priced, I say buy this one.

Update: This is a Great meter if you want to be fooled into thinking you are EMF free- It doesn't pick accurately up Many sources (or Not at all!)- Cell Phones, cordless 900mhz... phones, computers...! I read other negative reviews & bought the MUCH more sensitive Trifield 100 XE- Boy was I in for a shock (Ignorance is bliss!?)! Trifield 100XE EMF Meter ~~~~~~~~~~~~~~~~ Original Review: I wanted an inexpensive/ HIGHLY SENSITIVE EMF detector, and this is it! It is more sensitive on than other detectors costing $3x (.1)! This unit is well made (sorry that the 1 negative reviewer was probably bummed out at not finding a ghost...!), and 3.5' cord makes scanning EASY! Sturdy enough for a contractor..., with TLC! The other positive reviewers pretty well covered the features... I'll post some of MY test results- Best on High, and results WILL vary by brand...!- - Found 1 improperly grounded 120v outlet= 4' before, and 2" after fixed. - House fuse panel was VERY HOT!= 6'+, and I'm glad it's WAY out in the garage! Walls don't stop EMF's! - Outlets/light switches= 2" before use, and all outlets on circuit are 3' if in use (outlets after used are 2")! - Microwave oven (vary by brand...)= 6' - Cell phone (I use mine infrequently )= 2" (HOT) at speaker "FRONT" ONLY! Same on or off, and I'll carry mine facing OUT (Experts say to limit calls to 10min, no kids (thin skulls/ growing brains...!)! Wish mine had a speaker phone! HMMM?- Tony Snow, and Ted Kennedy both died of brain cancer/tumors!? Wonder which side of their head? - ALL digital clocks- Large face= 3', and small = 1' ! - Desktop computer tower= 2' (low), and flat panel monitor= 6". - Laptop computer= Very low, but modem/router was 2'! - My Older 900mhz cordless phones/base station= Zero, on or off! :o) 2.4ghz+ cordless phones are supposedly VERY HOT(same frequency as microwave oven!)! - TV's- Older tube type= 4', and 46" flat panel LCD/digital= 1'. - Light bulbs- Filament= 6", and Fluorescent= 1". It is a relief knowing..., and kinda fun! Buy one & see (no, I don't own stock... in the company)! Scott :o)

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.

This product is soooo good! I bought this when my son was in 5th grade for his science fair project and he got such a high grade! This detector is so simple, yet so advanced! My son also used the EMF detector for his 7th grade science project and yet another high grade! All we have to do is point the sensor to where the most EMF waves are coming from, from the electronic device. Not only on 5th and 7th grade but he used it AGAIN in 8th grade! Science teachers love to see how kids can create projects that inform people about dangers of electro magnetic waves and the devices which emits the most. My son got the 2nd highest grade in his class a 98. I recommend this to any parent with a child who wants to test "Which electronic device emits the most electro magnetic waves?" (Hint hint, the question for the science fair project). This is a very simple device to use. All you have to do is plug in the sensor and turn on the device and make sure the device is switched to H to get the readings. Just use the sensor to detect electro magnetic waves in your house, or put it near the device you want to measure the EMF waves from. It is very easy to use and a very cool and a must have gadget to have if you care about the EMF waves in your house.

Cell Sensor EMF Detection Meter works great. It will show the person that is using the meter where the spikes of EMF are located. It is used in ghost hunting but it can also help chasing down electrical problems in the person's home. I was very surprised with the EMF that was coming off of my in laws fuse box before their house burnt down. This was a few years ago as well. The meter still works to this day.

Couple things I noticed about this device. First, it measures both RF (radio frequency) and ELF (extremely low frequency) together, with no way to test each individually. Second, it is NOT designed to measure cellphone tower radiation and will not detect them, only the close RF radiation of a cellphone. It couldn't really pick up on my 2.3 GHz cordless phone emissions either when it was sounding the dial tone, maybe that frequency was too high. But it wasn't designed for that either. It's sensitive to regular cellphones frequencies though. I also realized after buying, that since cellphones have to meet emission standards, there is not much point for me to measure its RF output other than to confirm it meets those standards... well, other than to see whether those things you stick onto cellphones to lower their RF actually works. Those are my only gripes. Now, onto the good points. If you follow the instructions, this thing will indeed give you a decent approximation of the radiated power output of a cellphone. So it's true to advertised claims. Where this device shines is as an ELF meter for measuring the vibrating magnetic fields around clock radios, power lines, computers, appliances, and home wiring. I tested the frequency response and it measures best ELF fields between 30Hz and 900Hz, sensitivity rolling off greatly outside that range. On the "high" sensitivity setting, it even registers sudden movements of the probe, which I think is the CellSensor cutting the flux lines of earth's magnetic field. So if you shake/wiggle the probe in a given space, you can get a very rough idea of whether there's a DC magnetic field there. Like if you wiggle it just a little above a magnet the meter will go off the charts. So when you do your ELF readings, be sure to keep the probe still if you want to measure just the ELF fields of things nearby, otherwise you'll get a false reading generated by stationary magnetic fields. So in summary, this was worth buying, but mainly only to measure nearfield cellphone emissions and ELFs from current-carrying devices. It won't work for detecting cell tower radiation, finding wifi hotspots, measuring wifi output, and it won't detect the strength of static magnetic fields unless you get creative and wiggle the probe. For those applications, I recommend a proper RF Signal Detector good for 50MHz to 6Ghz ( Professional Wireless RF Signal Bug Detector ), and for static magnetic fields look for a DC Gauss Meter. I haven't tried to detect ghosts with it, but it probably also ought to detect EM disturbances caused by alien ships hovering over the house, haha.
