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. ## Features - Multiple high sensitivity sensors installed for detecting Power line, Smart meter, Cell phone, Microwave etc. - Identify/recognize the common possible sources, such as Power line, Cell Tower, Microwave, Static etc. - Safety suggestion lets you understand current situation instantly. - Detects 5G network signal and RF up to 10Ghz - Built-in RF Spectrum analyzer and GQ RF Browser for real time RF monitoring. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07JGJ897T | | Battery Description | Lithium-Ion | | Best Sellers Rank | #14,202 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #6 in EMF Meters | | Brand | GQ | | Color | gray | | Compatible Devices | Computer | | Customer Reviews | 4.6 out of 5 stars 3,276 Reviews | | Frequency | 10 GHz | | Item Weight | 10 Ounces | | Manufacturer | GQ Electronics LLC | | Maximum Range | 10 Meters | | Mfr Part Number | EMF-390 | | Model Number | EMF-390 | | Mounting Type | Tabletop | | Number of Batteries | 1 LR44 batteries required. | | Power Source | Battery Powered | | Smart Home Compatibility | Not Smart Home Compatible | | UPC | 723794245272 723794245364 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** GQ - **Color:** gray - **Item Weight:** 10 Ounces - **Maximum Range:** 10 Meters - **Power Source:** Battery Powered ## Images ![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 - Image 1](https://m.media-amazon.com/images/I/61l-2OpLOHL.jpg) ![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 - Image 2](https://m.media-amazon.com/images/I/61lEgPEFfpL.jpg) ![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 - Image 3](https://m.media-amazon.com/images/I/71IH-8TGHpL.jpg) ![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 - Image 4](https://m.media-amazon.com/images/I/812JMf1HgcL.jpg) ![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 - Image 5](https://m.media-amazon.com/images/I/71ys3tLPNCL.jpg) ## Questions & Answers **Q: Is the 5g wifi signal the same as the new 5g cell phone signal? will it measure the new 5g phones? it is confusing: it says: "rf up to 10 ghz"** A: The 5G wifi is referring to 5Ghz Wifi, and it is covered by this meter RF band. The 5G cell phone network is referring to 5th Generation cell phone network, it is nothing to do with 5GHz, basically its base band is much higher than 5Ghz **Q: Will this device analyze a 5 gig wifi signal like it does a 2.4 or 2.5/** A: Yes, it does analyze 5 Ghz frequencies. If you are asking whether it will analyze 5G as in 5th generation Millimeter Waves, the answer is NO.. 5th Generation 5G will use frequencies between 30Ghz and 300Ghz... You can get one that costs about $40,000... As in, they are not available to the public . **Q: Can it tell you how much emf your cell phone emits?** A: yes it does, in 3 scales. some readings read a voltage per meter and another is electro-magnetic reading, I searched through alot and after receiving this I found it to be the best affordable technology in its class, and it even automatically identifies the difference between cell phone and power line EMF in digital readable format. **Q: All i want to know if this detector gq emp-390 will detect 5ghz wifi signal and 5g cell phone ?** A: Yes it will detect 5GHz signal but not in all modes of operation. If it is the predominant source then the general Radio Frequency RF mode reading will reflect it. If it is a source mixed with others than all sources will be reported together as one value (sum/average over time...unknown. most likely average). It will not detect it in spectrum analyzer, by frequency, and show it's individual power level. Spectrum analyzer will detect 2.4GHz wifi. 5GHz is out of range of spectrum analyzer as is everything greater than 2.5GHz. It might detect presence of 5GHz data packet bytes in digital mode but I don't know for sure, have not tested this. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Accurate EMF Detection Tool *by J***N on February 6, 2026* This EMF meter is incredibly useful for detecting electromagnetic fields in my home and workplace.

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. ### ⭐⭐⭐⭐⭐ Works pretty reliably! *by S***M on September 23, 2019* I was looking around for a reliable and reasonably priced emf meter and came across this one made in the US. My experience with many China made test equipment is that they do not last long or are not accurate and reliable (you get what you pay for). The beauty of this product is that it can give the readings of the EMF, EF and RF on the same screen with an audible alert if they reach dangerous levels. It can also be switched to dedicated screens to give more details for each type of field. It is nice and compact, the screen is bright and the display readings are clear. I have used this product for over a month now with no issues. I have learnt a couple of things like not to stand less than 2 meters from an operating microwave oven as it will slowly cook you from the inside with dangerous levels of radiation. The wifi router is another thing to look at as it does radiate quite significantly over certain distances. Best to put the wifi router off at night when not in use. Even gang plugs, with the wire rolled into a loop can radiate quite significantly at close range. Also, try not to sleep with the cordless phone or mobile phone too close to your bed. Interesting discoveries made from just purchasing the right tool. I would recommend this product to anyone looking for a good, reliable and reasonably priced product. ## Frequently Bought Together - 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 - Radiation Nation: Fallout of Modern Technology - Your Complete Guide to EMF Protection & Safety: The Proven Health Risks of Electromagnetic Radiation (EMF) & What to Do Protect Yourself & Family - TriField EMF Meter Model TF2 – #1 Handheld EMF Detector for 3 Types of Electromagnetic Fields: Radio (RF), Magnetic (MF) and Electric (EF) - Measure 5G, Cell Towers, WiFi, Bluetooth, & Smart Meters --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/86203288-emf-meter-advanced-gq-emf-390-multi-field-electromagnetic-radiation](https://www.desertcart.pt/products/86203288-emf-meter-advanced-gq-emf-390-multi-field-electromagnetic-radiation) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-05-19*
