You need to be looking at Volts Per Meter. So use the EF frequency. Also, the sensors for RF/EF are located at the nose of the meter.
Thanks for the review. I have exactly the same device and I am very happy with it. To be honest: I also checked some reviews and found out that some guys said it is not accurate, but I guess I was lucky. I just checked again the EFM meter with my smartphone while using youtube and checking some music videos. It really works. Very interesting also: if you switch back from 4G to 3G on your phone you will see waaay less radiation...like on 3G I have around 0.2-0.5 mWatts/m2 but if I watch the same video with 4G I have over 20 mW/m2. I also tested the device for electric fields it works, magnetic too. I checked the 5G cell towers. That device recognizes it automatically and I have easily 3-5 mWatts / m2. So I guess you just got bad luck.
But yeah, I also talked to 2 building biologists and both of them recommended me the Acoustimeter or safe and sound 2. But to be honest I don't wanna waste money for a more accurate device. For me, this one is good enough.
That's great to hear mate, thanks for sharing your experience
Here is a working one.

Is 2G only even better than 3G?
@@nataliebutler you do not have internet with 2G
Thank you for the demonstration. I think you testing is accurate. The metre should be showing different, higher, readings than it is. There is obviously something wrong with the metre. You should be seeing spikes in RF / EMR and you're not. I need to learn some more about RF and how to read these metres too. Thank you for taking the time to post. Very informative.
Good review mate! :]
Press the right button and choose All in one mode, and with the third button you can flip the measuring wheel to switch between EV, RF, EMF.
I am using the Cornet ED88TPlus, and pretty happy with it. Goes up to 8Ghz only though. Would love to own a Safe & Sound Pro II, or maybe a III when it's available. Would be so cool, if you got a hold of a Safe & Sound meter to review for us.
Here is another video that shows EMF-390 testing the RF signal from a cell phone:

Nice one, thanks for sharing mate
Hi there, I ordered two of these to compare whether they worked ok and they seem fine but something odd is happening with my iPhone while on wifi. Although both meters detect RF constantly on iPad, this is not the case with my iPhone. For instance nothing is happening on the RF part of the screen (I always use the AllinOne mode) at this very moment (background level at 0.002 mw/m2) while I’m watching your video or writing this comment on my iPhone. If I do the same on my iPad, RF go up to 10mw/m2. Same when the iPhone is on idle mode. RF do not go up when I receive a WhatsApp notification for instance. However there is constantly something going on with the iPad even when it is in idle mode. Any idea why? Thanks!
You have to point the top of the device at the source and different source are designed to emit horizontally, vertically, or spherically. You may want to check out the direction booklet for more information.
Good review! Keep going on.
Thanks mate
i also just ordered/recieved this gq emf 390 meter and the default setting has the meter reading at every 3 seconds, i changed it to 1 second and it seems to register all pretty well. although i am still figuring it all out, my system seems to work. good luck, keep us updated, thanks for your perspective.
Excellent, thanks for sharing mate
@@headsoftech yeah your DNA is capable of healing it'self but this mechanism occurs while in REM Sleep, but you must also have a pretty clean natural diet as your cells prefer PhytoNutrients from leafy GREENS. love strong be well.
@infinateU wow thank you, that's some advanced tech info 😵
1 or 2 milliwatts or even 7 is still a massive amount of radiation. The Biolnitiative Report showed that biological effects started to happen at thousands of times less than that (i think they said that the effects were observed at 3 microwatts?).
Nice one mate, here's the conclusions of the report: bioinitiative.org/conclusions/
Right. 0.2 V/m is the safe limit. Looking at the EF setting, this meter works very well.
Except for the not very professional way of testing (not facing it the right direction), the major problem with many of these meters is they have certain drops of efficiency around specific frequencies. I suppose this one may have a drop at around 5Ghz. Other than that, since the display shows 2.458Ghz, it could be that you need to change some settings in order to check different ranges of frequencies.
Is it meant to detect frequency automatically. When you measured 5ghz your frequency displayed 2.4ghz
Could you tell me "2.4~10Ghz rate" of the air pods pro ?
Could you measure EMF of the brand new Buds live?
Interesting to learn that precision electronic tools made in USA nowadays are no more precise... That would be way dangerous in the Military Industry, if this pattern is also there...
Thanks.. I appreciate an honest review like that I found this to be very helpful.
Glad to help, let me know if you find a better one.
It is possible that you have a defective unit. I was getting a 10x EMF reading on my new EMF-390 next to my old EMF-360. Contacted GQ and sent back both meters. They found an out of tolerance resistor in the 390 and replaced it. They upgraded the software on my 360 too. I was very happy with the service.
I noticed you were setting the meter next to the computer. It needs to be facing whatever you’re trying to check, unless you are reading a three axis graph where you will see XYZ readings which should show on the Y axis.
Your resetting the meter has probably thrown it off too. In the big online PDF manual is states that you should use a professional Faraday cage to zero out the EMF.
My one works perfect, to read the RF you better use browser or spectrum, I recently bought it so maybe an evolved device?
I got one a few weeks ago. I cannot say anything about levels (I don't have a reference to compare against) but my unit goes in frequency only up to 2.5 GHz, and there are missing bands in spectrum.
It also has software bugs, in vertical mode it freezes and needs to be restarted.
Close to my WIFI router it shows field level and RF power, but my router works on 2.4 GHz only.
On a good side I have detected a GSM cable in a building ( 800 MHz range )
Overall is a bit disappointing, but is a less than 200$ tool.
I didn't know this video existed on UA-cam! This is the meter I wanted to buy and cheaper than the one I am actually, by coincidence, waiting to be delivered to me this afternoon by Amazon! I am already disappointed the one I finally decided on as a compromise decision doesn't measure above 6 GHz, unlike the one in this video, but after a lot of toing and froing i settled for the Trifield TF2, even though of lower RF range and more expensive! Was and still am attracted to the histogram capabilities of this GQ meter, which the Trifield cannot do at al,l but I have consoled myself with the fact the histogram facility on that meter only covers part of the full 4G band in the U.K. where I live, missing off the top frequencies of the 4G spectrum., so I told myself that although I like and would prefer that facility, not covering the full 4G band makes that aspect only of limited usefulness for that reason! Having spent a lot of time trying to research which emf meter to buy, I have realized there is no perfect decision to be made on buying the perfect meter; the perfect meter does not seem to exist, and if it does it must cost more than £200 as I've not looked above that price point, so any buying decision up to that amount has to be a compromise decision! The Trifield I have settled for covers the U.K. 5G frequency implementation at present, but will be lost, as also the meter of this video, as further 'developments' after the present implementation of 5G here will be using spectrum much higher than the 10 GHz upper range limit of the GQ meter, so really the best one can do at present is to make the compromise buying decision I have referred to above. There is a website called https:/emfaccademy.com which I feel has helped me emormously in making my final decision. After spending much time 'going round the houses' I came ultimately to agree with the analysis of the person running that website, and come to believe the advice given there to be sound and reliable! Reading another comment further down in the comments here today apparently referring to notable RF innacuracies, I think I am glad I didn't buy this particular meter now, but I have no way of verifying the lab testing of this GQ meter referred to in that comment! Having received the Trifield meter from Amazon this afternoon, I have initially tried it out and it does appear to be of a very good quality and built to last, and is noted on it as being made in the U.S.A. It looks and feels solid and I am already impressed with things like the tightly fitting, sliding battery compartment cover, and the fact that although it takes a PP3 type 9 volt battery it does not utilize the usual press on pull off PP3 battery connector, which tends to physically wear with the number of pullings off and pressing back on agains, the manufacturer has used individual substantial sprung, plated connectors to exert physical force for reliable contact with the battery contacts instead, with some pressure force being needed to insert the battery; it is definitely securely held in place! Brent Collins.
I just ordered mine few hours ago and will arrive tomorrow. I'll play around with it and see if it works or not. At worst, I'll send it back to Amazon where I got it from
Well, how did you get on with it? I've read Trifield TR2 is the best from the affordable EMF meters. So planning to get that one.
Hi, if I send you my reading will you help in understanding the result please.
Hi my friend, i also have a GQ EMF 390v2, but i have no problem with the readings, i test alot here in our house, and when i test my phone browsing youtube with this device just right next to it i get huge values, not like what i see in your videos, try contacting their support, maybe you have an uncalibrated device or a defective device because i get really high values when i get it just beside my phone when browing youtube, and i test alot, and i can see that my device is working fine, just try to contact their support because i can see my device is okay.. Just try to contact their support maybe its a firmware bug or a hardware defect, i already had 2 previous firmware updates with my device..
Do you still have it? could you tell me what version of firmware do you have? when I put the meter next to the cellphone it goes down, so I think it has a fuzzy logic to show less radiation if comes from a cellphone and its high
The sensors are to the rear of the unit. Noticed you holding it covering the sensors with a hand and testing devices by placing it next to a device instead of in the sensor field. That may be the problem?
I don't have this unit anymore, but let me know how it goes for you.
@@headsoftech Thanks for your reply. There is always the possibility of a defective unit. I found it's a good piece of kit for me. Amongst differentiating between power lines and Wi-Fi. It identifies cell towers. Even comes up in text it's a cell tower you are detecting. Great for finding hidden ones disguised as something else or concealed. They are getting very creative. I've tested it on known towers and other power consuming artefacts it picks them up beautifully. As for more finer detail on devices I haven't dug deep. That other device you had looked pretty neat. One piece of advice to anyone else reading this is never use a cell phone as it's charging. The EF shoots right up to concerning levels.
Did you read the manual?????
Look, BR68 says the max safe RF is 10mW per centimetre squared.
Does it have high/low frequency detection setting?
Hey mate, it's not high and low, but has got two readings, one for up to 2.4GHz (top one) and up to 8GHz (middle one).
Put it in the Correct Mode.
Set it to the Proper Frequency Band.
To make accurate measurements, you have to know where the sensors are and orient them correctly, otherwise the measurements will not be correct.
Not a very helpful review - in fact, it's just really confusing, when you've seen a test like this with a signal generator:
ua-cam.com/video/4ZzxHG9GW1Y/v-deo.html
As you can see, it works considerable better (even for pulsed signals) than one of the more popular meters.
Did you read the manual? This instrument uses a directional sensor, not an ambient sensor. If you're posting reviews, you ought to understand the difference. In at least some of your tests (at least the laptop test) you're holding it wrong - the front of the device should be pointed at the source. The manual explains where the sensor is and how to point it.
That said, it's possible you did get a dud. In the WiFi test at least, it appears to be pointed directly at the source.
Even then, this is not a helpful review, just confusing. Please consider returning the device, since you believe it's defective - take down this video and post a review of a working unit instead?
What kind of character you are performing Like cool impressing Mafian dude
strange for me the phone, wifi and also power lines plus even harddisk all worked to detect :)
Thanks for your true and honest review and saving our time, energy and money. Been researching everywhere for months and I am more puzzled as it is extremely hard to find a good one to buy as one review contradicts another review; thanks again.
A good idea is to order a couple from easy to return suppliers, that way you don't waste your time with just one. Test them out using logical RF emitters like your Wifi router/microwave oven/smartphone and return the worst calibrated/faulty devices.
Mine works just fine.
Im pretty sure that the spectrum analyzer is only for around the 2.4ghz range. Id use the .24-10ghz range for your overall readings. But good god man I could not live where you live. Those are too high for me. im not hypersensitive but I notice the effects on my body at those levels.
yeah pretty sure that broken I would definitely get a replacement
I read that to measure about 2.5GHz requires pressing going to the RF menu and pressing and holding a button. As you were not doing that, it did not measure it.
Stop touching the items together. your making a circuit. If you want to touch test the item youll need a probe.
Good Luck.
I just got one it doesn’t record phone radiation that’s why you can buy it on Best Buy USA
Hey, we need a meter that can test 60ghz to 300ghz range which is where 5g will be operating, I have been trying to find an economical unit that can read these ranges, the only unit I found was a very expensive 10,000 dollar unit which is just too much for the average person if anyone interested its this model by SAF J0GSAP6001 but we need a unit that cost under 500.00 so we all can go out testing for this 5g and get a better picture of where it's showing up. I dont trust these 5g maps and think it could be showing up in hidden places. any thoughts??
Over here in Australia we have the RFNSA[1] which lists all the cell towers and publishes their test reports, sometimes they're a decade old but they seem to be pretty reliable. I recently got another meter and it seems to be solid too, just posted a video about it. Which particular 5g map do you use?
[1] www.rfnsa.com.au/
@@headsoftech I dont really rely on the 5g maps, I look at them from time to time to see accuracy and sadly I have seen 5G towers up in certain areas but it would not show on the map. For instance why on earth would they put a 5G node smack dab in the middle of a old age community, yea sure folks in thr 70-80 need high-speed internet, it's disgusting what they are doing i have seen this more than once done. They are experimenting with old people to see what kind of harm and death they can cause plain and simple. ill check out your new meter you review Thanks!
@@headsoftech GQ EMF-390 is good but we need 60GHZ and above which is where cell death occurs. If a new 5G cell phone can receive these high frequencies than its possible to have a device that meters these levels.
Weird. My unit works perfectly fine for now.
Excellent, thanks for reporting
@@headsoftech not sure if it works perfectly, as I don't have other meter devices to compare it, but it works definitely. Thank you for your video :)
Review the Safe and Sound Classic or Pro RF meter. Its pretty good 3rd party verified
Nice one, will have to see if I can source one in Australia.
@@headsoftech or have a buddy from Canada or the US ship it in 👍
Got myself a safe and sound classic, I'm in Europe but couldn't find one here. I had to buy it from their official site (Canada). But I don't really care because this meter is awesome. Extremely accurate, very informative.
I calibrated the alerts to the measurements for the high level - not recommended for long time stay. Watch more Yt videos. C: regards
You are supposed to calibrate the unit before use. Duh.
i have one or a similar model.. get in touch with the manufacture and learn how to use it .. theyre complex machines and u do need to know what your doing with it ..and best way to do that is by playing with it and spending time using it in different situations..amazon reviews cant be trusted at all anyway ..
Does it measure 5g
Just basic 5G, the full spectrum goes over 10GHz
This is seeming like user error.
Not possible
Mine was poor too
Maybe is faulty or settings not correct. Below link with happy owner

Your supposed to point the back of the meter to what you want to read.
This has confused me, not helpful.
You are using the device wrong
Nah, not going to get that thing.
I purchased this meter last year and returned three days later for refund. Not accurate compared to other more expensive meters. Customer service not helpful.
Looks like a fake meter.
Reasonable meter for measuring electric fields, (down to 1 V/m) can't detect any magnetic fields below 60 nanoTesla's, (0.6mG) so that makes this meter useless right there. But when it comes to measuring RF, that's when this meter becomes a con-cern, as its sensitivity on the main display, THAT MOST PEOPLE WILL USE, is the worse on the market, even more worse than the TF2 for measuring RF. Unless you know how to use the RF spectrum analyzer functions on this device, for extra sensitivity, your screwed. Lots of fun to play with, but no good for sensitive people looking for EMF hot spots.
You're EMF paranoia getting the best of you. According to the meter specs detects from 0.0~500mG, 0.0 to 50µT. You're dreaming to get reading less than 1mG anywhere near a city..even if you were the boy in the bubble 🤣 If anything the meter range is too low, should go up to 999mG. RF range is: 0.02µW/m² ~ 9999mW/m², Detectable Frequency: up to 10GHz. TF2 sucks, GQ has tested better than most by many others.
this device is totally inaccurate, i would say its a good fake that worth 20$
