Like the mosquito alarm?** A: No, only EMF / RF, electro magnetic spectrum not sound waves **Q: Will this equipment detect electricity pylons for say up to 1 mile ? (i want to know before I purchase a new house)** A: It really depends on the strength of the electromagnetic field being generated. An electromagnetic field decreases exponentially over distance, as a result I would suggest that a pylon carrying 400KV a mile away would be undetectable over the earths natural magnet field. This device is capable of detecting emissions from TV's, computers and other electrical systems within the home. So in short the answer is no. If the pylon your concerned about is about a mile away I'm sure it would have no detrimental affect whatsoever. **Q: Can this device function as a Geiger counter in the event of a nuclear incident please?** A: No, definitely not. It measures electromagnetic radiation up to 10GHz, not nuclear radiation. It is mainly useful for detecting dangerous levels of non-ionising radiation from mobile phones, smart devices in general and. Microwave cookers etc. They do a Geiger counter version that does detect nuclear radiation. It detects beta and gamma radiation that would be emitted by a nuclear explosion but not alpha particles resulting from breathing in radioactive dust. However, beta and gamma radiation detection is generally the best indication of a nuclear event. **Q: What is the maximum time period of data that can be recorded on onboard flash memory and transfered to PC?** A: It is about 24Hrs for every seconds data. ## 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.co.uk/products/93934272-emf-meter-advanced-gq-emf-390-multi-field-electromagnetic-radiation](https://www.desertcart.co.uk/products/93934272-emf-meter-advanced-gq-emf-390-multi-field-electromagnetic-radiation) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-21*
