Three types: EMF meters detects three yypes of EMF pollution, AC magnetic, AC electric, and microwave
Auto Sound and Tricolor Bar Alarm: Tricolor bar will turn green, yellow, and red, automatic alarm triggers above the safe value (250 V/m or 5 uT/50 mG or 50 mW/㎡
Easy to Use: Operate with one hand and move or make field measurements(You have to hold the EMF METER to make a test)
Mute Function: The device can be muted to prevent scaring ghosts away. or when you’re testing some quiet areas, you can turn off the buzzer first, avoid disturbing the others
The device features an automatic shutdown after 15 minutes to save battery life. If you need continuous measurement, you can disable the APO function: Press and hold the “APO” button to turn off the auto power-off feature
Illuminated Screen: Designed with an illuminated Tri LCD screen to aid ghost hunting in the dark
When measuring the electric field, it is essential to hold the device in your hand. This is because the human body acts as a grounding source, ensuring more accurate readings. If the device is placed on a surface, the measurements may be inaccurate due to environmental interference

How far away should we stand from a microwave or sleep from charging electronics?
EASY to use, it automatically “BEEPS” when walking or driving by high EMF areas. Turn it on, place it in your purse or belt and go explore around your property or home! This is a really helpful tool to alert you to harmful locations of equipment nearby which might need attention for relocating away from you and your pets! Came with batteries! Works immediately out of box and has EXCELLENT “how to” manual for beginners! Great quality too. Shipment was very fast as well.

Worth it.
I love this meter and it works great, but ignorance is bliss right? Depending on how close you are to certain “towers” this thing will make you mad, not because it doesn’t work, but because it does work and it alerts you to living or traveling through an area that has ridiculously high levels of RF. FYI I made a video on social media using this meter and it was removed. I wonder why? Good meter, good price.

Reliable EMF Meter with Useful Features
I recently purchased the EMF Detector to assess electromagnetic radiation fields in my home and office while I tinker on projects. Here’s my experience with the product:Timely Delivery: The product arrived on time, which is always appreciated.Packaging: While the package was slightly damaged, the device itself was unharmed. It would be great if the packaging could be improved to prevent any damage during transit.Battery Reminder: One thing to note is that you’ll need to buy batteries separately. Make sure to have them ready when your EMF Detector arrives.Color Display and Measurement Options: I really like the different color display on this device. It’s easy to read, and the ability to change measurements (e.g., milligauss or microtesla) is a useful feature.Alert Indicators: The color-coded alert indicators are a standout feature. Here’s what they mean:Green: Everything is good and safe.Yellow: Elevated readings—be cautious.Red: Dangerous levels—leave the area or take additional safety measures.Multiple Uses: I purchased this tool for various reasons:Setting up a temporary Faraday cage.Measuring homemade antenna functionality.And, of course, ghost hunting in my house!Overall, the EMF Detector has been a valuable addition to my toolkit. It’s reliable, easy to use, and provides essential information about electromagnetic radiation. While there’s room for improvement in the packaging, the device itself performs well.I hope this review helps potential buyers make an informed decision! 👻

E-Z Straightforward Operation
E-Z Straightforward Operation. Large clear visuals. High sensitivity and accuracy. Handheld and comes with nice carry bag, though I keep it in its heavy box. Great value tool.

Great product
Best purchase I’ve made in a long time. Works perfectly and easy to operate. Learned a lot about unsuspected emf emissions in my house including a digital clock and two bedside lamps that I loved and used constantly that were touch-control with 3 brightness settings and now I know emitted too much emf. I’m trying to figure out if there’s a way to use them going forward or just pitch. I wrapped my iPhone with 3 layers of aluminum foil underneath its case which alleviated almost all emf emissions and my neighbor came over with her iPhone and we tested it with this emf/rf detector and it went crazy. I offered to loan it to her to test her own household belongings and she replied she didn’t want to know what’s lurking there. I’m going to order one of these for my daughter so she can also choose how safe she wants her surroundings to be with all this horribly unhealthy modern technology invading every aspect of our lives we’re unaware of.

An eye opener if you are unaware of how strong Wi-fi and electromagnetic fields can be.
A concerning, but widely unknown fact is how strong cell phone signals, Wi-fi, and electromagnetic fields have become over the last three decades. As any competent Biology professor will tell you, a human body is an electro-chemical machine utilizing electrical impulses through nerves to move muscles, feel pain and pressure. Chemical actions within a body regulate cellular activity, hormones, break down food consumed into usable components, etc. Interference with those vital function can and do cause problems.Keeping all this in mind, Cell phone signals and Wi-fi utilize wave energy to operate. Wave energy can range from microwave, x-ray, radio waves, infrared and ultraviolet waves, essentially across the entire wave spectrum. For example, a Microwave oven uses microwave energy to make molecules vibrate rapidly creating heat, that cooks food, such as ‘meat’ etc. Meat is ‘muscle’ tissue. The metal sheet with small holes in the glass of a microwave creates a ‘Faraday shield’ through which microwave signals cannot pass.As the wave strength of Cell phone signals and Wi-fi increases, the potential for disruption in Human cells increases exponentially. This is also true for Electromagnetic fields. Computers generate powerful magnetic fields. The strength of these fields decreases rapidly over distance, so the closer to the source, the stronger the magnetic energy.Cell phones contain very powerful, miniaturized computers! They therefore create powerful electromagnetic fields.This device/tool can measure the strength of all these wave signals.Now, the eye-opening part. Turn the device on while standing away from your cell phone, W-fi router, laptop, or Apple computer. You will notice that the various type of signal strengths displayed on the meter either reads zero, or very, very low from background sources.Then move the device closer and closer to the cell phone, computer, router etc., and watch the numbers (signal strength energy) skyrocket. As those numbers increase a series of lights change from green to yellow, and the red light meaning extremely powerful.I have measured my iPhone 15 Pro, our whole house Netgear router, and pc.For all of them the signal strength goes ‘off the charts’ as you get close. Within two to six inches of the cell phone the cell signal, microwave band, and electromagnetic readings are alarming! The other devices are the same – alarming.Imagine the potential harm these can do to at the cellular level in your body (such as your brain), if held close for extended periods of time, or continual exposure such as having your phone on your hip all day, or in your pant pockets, close to reproductive organs. Think microwave cooking type damage.The GOOD news, this meter can detect the distances at which the signals can be dangerous, AND Faraday cloth, or blankets can totally block all these signals. Do some research and get some of these Faraday shield materials to protect yourself, and your children.There are many types of Faraday shielding materials such as very light cloth, and blankets sold on Amazon. A word to the wise . . .

Works great. Detects what it’s supposed to. Was going to buy some blockers and will update.

el panel es claro , avisa con pitidos

Worked perfectly for the measurements I needed to take. I was most surprised about the EMF field around extension plugs. The magnetic field around them is incredibly powerful so be mindful if working near one like I do. It’s easy enough to use and decent quality so value for money in my opinion compared to some of the other options on the market and silly money.

Détecte bien les différentes pollutions EMF, quand à la précision de l’appareil je n’ai pas de moyen de comparer, en tout cas il faut utiliser une “pince isolante” pour tenir l’appareil sinon la mesure est faussée par le contact du corps humain et ça fait une grosse différence.
