This device can help you to check whether there is no radiation and constant temperature around the object under test, but it can not directly detect the RF value - MULTIPLE FUNCTIONS --Test the average or peak (maximum) readings, and hold the data for viewing with one key. The large backlit LCD screen is clearly visible and easy to observe. Automatically power off after 5 minutes of inactivity - SOUND & LIGHT ALARM - when the test result exceeds the safe value (> 4.0 mG / > 0.4µT / > 40 V/M) the screen turns red, the indicator light flashes, and a buzzer alerts you. If you think you it beeps noisily, you can choose to turn it off - LARGER FREQUENCY RANGE WIDER APPLICATION-The use of advanced electromagnetic radiation sensor, frequency range: 5HZ-3500MHz, coupled with accurate measurement chip, so it can be widely used to test TV, computer, printer, microwave oven, refrigerator, cell phone towers, for low frequency household appliances, and ghost hunting, etc. - CUSTOMER SERVICE - we strives to create professional and high quality meters.

I live a crossed the street from an old children's hospital and my house has always been haunted. Now I know when the ghost or ghost are in the room. It has made living with them much easier as I can now talk to them, because I know that they are there. Its seems like they cause much less trouble, now that we are friends. Well worth the money it is a must buy, if you think you have ghosts. ### ⭐⭐⭐⭐⭐ Ease of use. *by P***. on March 18, 2024* Gift for grandson. Budding scientist. ### ⭐⭐⭐⭐ Don't have a trifield to compare it to, but it works for me *by X***P on May 10, 2024* Easy to use, has decent coverage, so I'm satisfied, it works in my application. --- ## 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.vu/products/451890398-joauiax-emf-meter-reader-emf-detector-5hz-3500mhz-digital-household](https://www.desertcart.vu/products/451890398-joauiax-emf-meter-reader-emf-detector-5hz-3500mhz-digital-household) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-04*
