EMF Meter,Advanced GQ EMF-390 Multi-Field Electromagnetic Radiation 3-in-1 EMF ELF RF meter, 5G Cell Tower Smart meter Wifi Signal Detector RF up to 10GHz with Data Logger and 2.5Ghz Spectrum Analyzer

This EMF meter is incredibly useful for detecting electromagnetic fields in my home and workplace. The 3-in-1 functionality measures EMF, ELF, and RF radiation with impressive accuracy. The digital display is clear and easy to read with both numerical values and a signal strength bar. The audio alarm feature alerts you when levels exceed safe thresholds. Compact and lightweight design makes it portable for testing different locations. The battery life is excellent. Perfect for identifying sources of EMF exposure around electronics and appliances.

This meter may be a lifesaver. 2 months ago I had installed a new security camera basestation in a cabinet in our family room where my family spends most of our time. When I got the EMF meter and moved around our house I noticed extremely high and likely hazardous RF (many multiple times that of our WiFi) coming out right by our heads from this camera basestation. I wish I had bought this meter months ago! I changed the default settings on the basestation and was able to confirm with the EMF meter that the levels are now safe. Then I discovered very high EF readings where one of my kids sleeps! Turns out there’s a live wire in the wall by the pillow on the bed, and I was able to fix that situation by unplugging devices from that circuit and confirm using the meter that the issue was solved. I’ve owned this thing for two days and already it’s alerted me to 2 potentially significant health hazards! 5 stars from me and I’m recommending to my friends. Also, the device itself is easy to use and I love how it shows EMF, RF and EF levels separately.

I found out a lot using this little device, and made some changes. I used to keep my iPad directly in my lap, usually plugged in (with a long cord) when I was using it. Not anymore! It's screaming hot when you measure what's coming off of it (alert went off consistently and it was well over what was considered safe). I plug it in now across the room; and unplug it to use it, and then only on a pad. This device measures RF, ELF and EMF. It's good not to forget any of them. It's cheap and it really works!

In the vertical position this meter gives false, peak RF readings as high as 3442 µW/cm2 I bought the EMF-390 to evaluate my home and radio shack for RF energy. I’ve been an amateur radio operator for 10 years and I’ve been curious about the RF level from my equipment. The price was reasonable and even if it was not perfectly accurate it would find any areas of concern. Good enough. One thing I noticed the first day was some very high power density pings the meter was detecting. I have it set on µW/cm2 and the FCC exposure limit is listed as 1,000 µW/cm2. I have had several peak readings at 3442 µW/cm2 ! That’s very high. The 3442 seems to be a device internal limit. I checked everything in my house and even touching my wifi router gave me a reading of 108 µW/cm2 . After several days of pings between 200 and 3442 and not being able to identify where these pings were coming from I bought a Tiny SA. I live in a rural area and the nearest cell tower is over a mile away. My house is 200 feet off the road. For a week I have been scanning frequency chunks with the spectrum analyzer. 100 kHz up to 10 GHz. Small bandwidth to keep the scanning time under 500ms. I’d let the scan run for a couple of hours with it holding max readings and then up to the next frequency section. I found nothing that could explain the EMF-390 peak readings. After some AI assisted research, it seems the EMF-390 is known to give some false readings when in the vertical position. It still happens occasionally in the horizontal position but not as often or anywhere near the magnitude. All in all, its a nice, sensitive meter and I have recommended it to friends.

Amazing device and came fully updated. While reading the manual I got a text, this thing detected it, threw a beeping alarm and told me what it was. I was like wth lol and it was 2 feet from the phone at least. So far it tracked down the RF I was getting in my dj equipment. Turned out to be an old school ceiling fan lmao. Also found a wiring issue with the ac lines we didn't know we had. Great device and easy to use. Cash well spent.

I grabbed this after a friend was talking about potential EMF effects on the human body. I was surprised to see how much some mundane items like desktop fans put out. Of course, it's subjective as the card says its high, but there isn't much evidence that it's actually harming us. That said, it can't hurt to reduce the exposure of all of the EMF we're subject to, and which our bodies weren't designed to deal with in nature. It's also nice to have to check around microwaves to ensure they aren't leaking. It seems to be accurate as it quickly adjusts the levels as you put it near sources of EMF. It's portable and rechargeable so it's easy to carry in the glovebox or just keep in a drawer for when you want to check something. It's just one tool to provide you with some data about your environement.

The GQ EMF-390 is much smaller than I expected. I know the dimensions are listed but I didn't pay attention to that. It's only about the size of a large smart phone but thicker like an old school pocket radio. The battery is removable and is a standard 18650 like the ones large box type vape devices use. It comes with a USB cable for charging and computer communication. Also comes with a black draw string pouch for storing your meter and a credit card sized EMF, EF, RF radiation safety reference guide. Some folks say it isn't for beginners but I disagree. This device is self explanatory. You turn it on by holding the power button for 3 seconds. Point it at what you want to test and it displays a numeric reading. If you don't know what the numbers mean it also says normal, medium, high, or extreme. Also the higher the numbers go the faster it beeps. Idiot proof. One reviewer complained that it doesn't detect in 360 degrees. I felt that way at first but now I think front detection is better. This way you better pin point the source of your readings. Another reviewer stated he was not sure his meter was new because his meter arrived with a full charge and the time and date set. Well my meter also arrived fully charged and with correct date and time but it was in a sealed plastic bag and had a protective plastic shield on the screen, the type intended for shipping that you are supposed to remove before use. So I'm guessing they all come charged and set up, ready for action. The shipping was fast!! I received mine 2 days after placing my order with their standard free shipping!

I’ve been using the Advanced GQ EMF-390 Multi-Field Electromagnetic Radiation 3-in-1 EMF ELF RF meter for a few weeks now, and my experience has been mixed. Functionality: The device offers a wide range of features, including the ability to detect EMF, ELF, and RF fields, making it versatile for various applications. The inclusion of a data logger and a 2.5GHz spectrum analyzer is a nice touch, adding to its utility. Design: The EMF-390 is compact and easy to carry around. The interface is user-friendly, with clear displays and straightforward navigation through its various functions. Detection Range: It covers a broad range, capable of detecting RF signals up to 10GHz. This is particularly useful for monitoring modern devices and 5G cell towers, which operate at higher frequencies. Convenience: The built-in data logger is handy for recording and reviewing readings over time. It’s especially useful for tracking changes in EMF levels in different environments. Build Quality: The build quality is decent. The device feels robust and durable, suitable for regular use without the fear of it breaking easily. Accuracy: Here’s where my main concern lies. While the device seems to pick up signals and display readings, I’m not entirely convinced of its accuracy. Some readings fluctuate significantly without clear reasons, making it hard to trust the data entirely. This inconsistency raises questions about its reliability, especially for critical measurements. Value: For the price, it offers a lot of features. However, the uncertainty regarding its accuracy makes me hesitant to fully rely on it for precise measurements. Overall, the Advanced GQ EMF-390 Multi-Field Electromagnetic Radiation meter is a decent tool with many useful features, but its accuracy is questionable. It’s a good starting point for general monitoring, but I’d recommend verifying readings with a more reliable instrument if precise data is essential.

I tested the device under various conditions, and the build quality is excellent. I really like this type of display because it’s highly energy-efficient, and the screen remains perfectly readable in direct sunlight even without the backlight. The readings appear to be accurate and realistic, unlike the phantom readings I used to get with my old BR-9A. Another major advantage is that the battery is removable, and it uses the widely available 18650 cell. That’s a huge plus in my opinion. Overall, I’m very satisfied with the device. The only thing I didn’t like is the way the PC connection is implemented. The software feels rather unfinished, and without a proper data logging feature, connecting it to a computer doesn’t offer much practical value. Hopefully, future software updates will address this issue. That said, this is only a secondary feature. I definitely recommend this device—at this price, I simply couldn’t find anything better! 🙂👍

高エネルギーの充電式リチウムイオン電池が使用されています。 電磁波過敏症の重症者は、充電式リチウムイオン電池から放出される低周波電磁波で 病状が悪化しかねないので、お勧めしません。 高周波と低周波の両方を測定できるなど性能はよいので 普通の人には問題ないと思います。

Very good instrument and very fast and accurate delivery.

Lo he utilizado únicamente para medir la intensidad/densidad de las ondas electromagnéticas emitidas por una cocina de cuatro placas de inducción (para ver si podía cocinar sin riesgos después de la implantación de un marcapasos). Y el aparato ha sido muy sensible en la medición, diferenciando claramente entre lo emitido por cada una de las cuatro placas, así como mientras me alejaba/acercaba de cada una de ellas. Inconveniente menor: el manual de instrucciones no viene en español/castellano.

What amazing was knowing how much EMF is emitted during charging of mobile phones. I was charging my mobile at bed side before I had this detector. Once I saw the Extremely high EMF from the cable and that charger, I stopped charging overnight next to my bed. Was also suprised that Hyundai Ioniq 5 EV does not producted much EMF during driving, but didn't have change to test when the vehicle was on charge. I am able to know how frequent the mobile phone tower was communicating with my mobile phone. Not to put mobile phone on trouser pockets due to high RF.
