Defective Meter/Horrible Experience
You may receive a functional meter from GQ Electronics. But, this is by no means guaranteed, and good luck getting your problem resolved if you get one of their bad ones!As a Senior Computer/Electronics Design Verification Engineer now working as an EMF Consultant, I know well how to determine if electronic hardware is defective in general (and EMF meters in specific), and the GQ-EMF 390 I received is clearly defective (details below and in the attached pics). For the same reason, it's also obvious to me when a manufacturer's Quality Control and Debug processes are broken: In this case, GQ Electronics allowed a defective meter to be shipped out not once but twice, they have repeatedly failed to properly identify/debug/fix the problem, and they're *still* wasting my time and energy with ridiculous, condescending and redundant run-arounds, instead of owning the problem and replacing the broken meter. Ego? Incompetence? Both?)As you can see from the attached photos (also sent to GQ Electronics), for example, the meter I received shows an RF reading of 0 mW/m2, in both "RF Browser" and "All-in-one" modes, even when placed right next to two transmitting RF sources (cordless phone handset and base station). For reference, you can see my known-good Cornet meter in the same pics, set to the same units, showing the proper RF readings. One would think this would be enough verification for them to recognize the problem and take responsibility for doing right by their customer who's debugged and verified the problem for them. But, amazingly, no....When I sent the broken meter back to them, they called it "user error" because the meter happened to be in the mW/cm2 units (which I tried as a last resort when it only ever read 0 RF in mW/m2). As I've told them repeatedly, the meter has never registered an RF signal - it reads 0 RF in all RF-detecting modes, orientations, and units, even when right next to any type of RF radiation (cordless phones, wifi, mobile phones). But, they just ignored me and gave me a condescending lesson on the difference between the units settings (mW/m2 vs. mW/cm2) and sent the defective meter back to me, without even testing it (obviously).Now, even after viewing the photos, they've denied my second request to return the still-defective meter..instead giving me the run-around...saying that because of the location of the sensor, I should try different orienting the meter in different ways. Not only, as I've told them multiple times, does the meter read 0 RF in any orientation/units, but if one of their "working" meters cannot accurately detect an RF signal right next to TWO TRANSMITTING RF SOURCES (cordless base station and handset - see pics), then it's useless: Ie, if this is how one of their "working" meters functions, then your health is very much at risk if you rely on the GQ-EMF 390. But, I think the meter's truly defective, they just won't admit it, and this is just one more ridiculous and redundant run-around, wasting more of my time and energy, avoiding the problem, and leaving me with a meter that's useless for RF Radiation.Speaking of more ridiculous and redundant run-arounds: The first thing I asked on the phone when I called in originally and was told I needed to return the meter was, "Are there any possible firmware fixes I could try before sending it back?" Joseph told me, "No, it's a hardware problem, you need to return it."So, now, they're asking me for the serial # and firmware revision #...saying maybe it needs a firmware update. First of all, this was already checked (by my request before) I originally returned the meter. Second of all, don't they check this before sending out a meter in the first place...and, especially, when a meter's been returned?! (Again: Broken Debugging methodology, as well as broken Quality Control practices...not to mention the breach of ethics and professionalism.)So, you can expect nothing but headaches and unnecessary, unscrupulous, buck-passing run-arounds from GQ Electronics if you get one of their defective meters. They won't do the right thing by you by owning and fixing the problem. Instead, they'll blame you for it and waste your time and energy in avoidance tactics. I wish I'd never ordered it, and hope to make others aware of the risks of a similar experience if you order one of their meters.My experience doing business with GQ Electronics has left me angry, fed up, and very unsatisfied -- Beware!
a basic test device well worth having around!!!
I tried to download a better manual from the web site but only found them for other models, not this one. One thing I want it to not do is auto rotate the screen every time I move it slightly. Very annoying when trying to read the display!! (An email to the company told me the rotating display is called "swivel" and can be turned off the auto mode. They also sent me a link for the proper manual in easy to read PDF... now they can have that 5th star!!!!I was a radio communication tech for 35+ years so I'm pretty picky on how test equipment should work.But it seems to work as advertises. I have a state police 800 meg (30 channels trunked) radio tower with microwave dishes all over it in my neighborhood. . This unit told me my home was not in any strong RF fields from that tower. (My friend who lives much closer lives in a 24/7 RF bath that is truly scary)This unit did quite well at picking up power line EMF, the biggest problem in my home. The Dell computer tower under my desk (pretty much radiating EMF between my legs) was a huge offender and just had to be moved. The computer in my bedroom is a better Dell and had nearly zero radiation. My WIFI was well placed but if your WIFI sits close to you where you sit, move the dam thing so it is at least several yards away (around the WIFI box the RF field is quite strong). (low quality LED and more industrial home/office florescent lights may surprise you and how much EMF and RF they put out)I'm not so sure this unit is good at picking up the intermittent pulses an idle cell phone constantly sends. They do cause the meter to respond but because they are pulses the meter averages them. If you or a child sleeps near a cell phone test/measure its RF output when the phone is on a call.... it puts out that same amount of power in its pulses (and its not healthy, in fact pulsed power can be worse for you than constant power).Will this work on 5G??? Most 5G will be above its operating frequencies but it should pick up the constant pulses as rf or EMF. (There is nothing good about 5G and its constant "milometer" wave frequencies and constant digital modulation pulses. .. fight to keep it out of your area, if you loose that fight (and you will loose) ,,,MOVE or try to shield yourself from the 100% area/busines saturating signals... that is predicted to be in place and operational nationwide by 2020!!!!!
GQ EMF-390 good but can be better if further improvement
I really like GQ EMF-390 due to the following points: 1. It shows all kinds of EMF in one screen, so I can judge fast which one is in danger zone. 2. It analyzes very clearly the change of each signal in realtime. However, I would give it 5 stars if it can detect 360 degrees like a well known brand in EMF detector. Only if you point the device directly to the EMF source, it shows the signal, otherwise, the signal is quite weak. So if you want to detect a possibly dangerous EMF source, remember to scan it 360 degrees.
Great little product for the price
I compared specs for a range of meters and this had the best set of capabilities for the price. Having electric, electromagnetic, RF to 10GHz, and an integral multi-channel spectrum analyzer is a huge bonus. Yes, this may not be as precise as professional grade meters/equipment, but it is a great little device to check your home even as a coarse measure. The LCD on first unit I received died after a couple of days, but they promptly shipped me a new/repaired unit within a week. This meter is very telling in regards to checking your laptop, cell phone, cordless phones, microwave and anything near your bed (including an alarm clock that was giving off excessive electromagnetic field near my wife's head).
Works for what I have in mind
Using this tester I Was able to tell the amount of EMF, EMF and RF radiation in my bedroom at night. I also take it on trips so I can identify the radiation in the room and either unplug the emitting unit or cover it with a copper-silver sheet.I absolutely recommend this product.
This is a very capable meter at this price bracket and perfect for home use providing all the necessary information required for general use (a lot easier than using Hall effect sensors and an Oscilloscope), more capable meters are available ( commercial / professional) but at a much higher price and few are available as an all-in-one, usually separate meters for EMF and RF. If you are just looking to see what magnetic and radio frequency levels are being generated in and around the home by you white and brown goods this little meter is perfect i.e. Wi-fi, TV, Bluetooth, Microwave etc. The meter will also display whether the levels are 'normal or high'.
False sense of security from RF exposure
I found the promise of measuring all three types of EMF field very useful, but the key feature I wanted this for was to measure RF pollution in my house. The readings from a certain distance looked normal and I thought ok my router can't be that bad. Wrong the Acousticom 2 gave a too high reading from a distance and gave a better sense of security so this one went back.
Accurate and simple to use 3 in 1 (EMF/EF/RF) meter
This meter is half the price of equivalent competitors and provides everything a budding home worker or concerned parent could possibly need. Easy to use and sensitive enough to be able to easily sense check that the meter readings are reliable (which they are with mine). Super accurate in fact, especially when held correctly (as shown in small printed instructions). I wanted it to check my home office and particularly the electric / electromagnetic field fields and radio frequencies (aka WiFi exposure) at my desk & kitchen table (for home working under lock down). With some small changes was able to reduce our exposure to all forms of invisible radiation by more than 10 times. Also was able to see change in RF in real time as I used WiFi on my iPad. I already knew that you should not hold your iPad in your hands and use WiFi but the results were an eye opener. Needless to say my desktop computer is not connected by Ethernet cable and favoured (whenever possible) over the iPad. I have also move the modem (which is really harmful at short range, shit these things should come with a serious health warning!) as far from me as possible. This device is a God send and only after I had bought this meter did I watch 'Better Call Saul'. So glad I went for this meter and would recommend to anyone remotely concerned about their health with all the debate raging over 5G
leider in Sache Hochfrequenz sehr untauglich.
Es erkennt NF und das EMF, ob die Werte stimmen, lasse ich im Raum stehen. In Sache Hochfrequenz leider sehr untauglich. Ich muss das Gerät an den Router halten, damit es etwas anzeigt und Alarm macht :-) Ich habe für den Preis nicht sehr viel erwartet aber wenigstens etwas Sensibilität für hochgrequente Strahlung wäre TOP um zu wissen ob die Abschirmung etwas nützt oder nicht....Ich hatte mal Gigahertz Geräte die ich verkauft habe weil ich sie nie verwendete aber das ist ein Unterschied wie Trabant und Merceedes S Klasse, nur mit dem Trabant kommt man wenigstens von A nach B...Ich beschreibe nur meine Erfharung aber ich hätte mich sehr gefreut wenn es funktioniert hätte weil die Fähigkeiten und Einstellmöglichkeiten sind 1A.
Lower priced meter that gives a good idea of radiation/ filed density.
I bought this meter because it was at an affordable price, many features and I hoped it would do the job of other more expensive meters.It's a good meter with many functions, but I'm not sure how accurate it really is. It will give a fairly good reading for all microwave and RF radiation and can detect magnetic and electric fields. The RF and frequency readings in different modes seem to be different, which doesn't make much sense to me. There is a manufacturers forum, but I've never been happy with the answers given, that don't make sense. However, at least there is a support forum for any issues.Maybe it's accurate and where I live, but I seem to get static field readings of 1000 volts near energized appliances such as a computer, but also were circuits are not energized and where there should be no electric fields. This seems way off. The manufacturer sent me a new firmware upgrade, but this didn't improve the readings. All I can say is you get what you pay for, when it comes to RF meters.
