When seeking sources for EMV related issues this device can be helpful. It gives you an idea about E and H field strength and its frequency range. However I can not tell the accuracy of the displayed values. Results differ when comparing with measurements from a spectrum analyzer or scope with E or H probe - not neccesarily because of the device but because of the nature of the observed fields.

It's quite astonishing how powerful (MF flashing) the magnet field from a separate Induction plate was, even 2 metres away, something my Soeks Impulse meter didn't seem to pick up!I was amazed at how much EF and MF, earthed metal cased PC's were giving off, especially one containing 8 hard drives.I found shockingly high readings (flashing RF) over 250mw/m2, even 20 metres away from a nearby Radio mast, covered with numerous loads of antenna, including parabolic and panel Microwave ones, and I suspect WiMax antenna too; I saw also saw shocking levels 5 metres from a nearby local hotel, possible from high power WiFi or a hidden cell tower. Fortunately my street and house it far enough away and shielded by several layers of houses, so I see relatively safe levels there.I got this meter because I wanted to see if I was/would-be exposed to hazardous EF/MF/RF from WiFi, Bluetooth, and 5G, when that gets rolled out. I haven't measured much or felt anything from Bluetooth, Logitech and Steel Series devices.Even with only my SOHO WiFi router set to only 30% power, with low measured signal strength, I've found that I feel subtly better and sleep better with it turned off, so I may look to use a more Ethernet cabling, and only turn on WiFi occasionally. I have very little WiFi only kit, so this isn't much of a problem, and most of my Android devices support Ethernet via an OTG adapter.

Cet appareil permet la mesure simultanée d'un champ magnétique statique (aimant), d'un champ électro magnétique (dispositif électrique, câble), et d'un champ radiofréquence (ondes radio). De petite taille, il présente une interface ergonomique et lisible, avec un pivotement automatique de l'affichage selon l'inclinaison. La batterie chargée via un port Usb dispose d'une bonne autonomie. Un petit graphe en temps réel permet de suivre l'évolution d'une mesure en cours. Des alarmes visuelles et sonores sont programmables pour la détection de seuils d'alerte.Le vendeur est professionnel et réactif lors de questions posées. Un forum constructeur est accessible sur Internet.Les mesures sont assez fiables, et les capteurs très sensibles. L'angle de mesure est à prendre avec considération car il y a un capteur XYZ. le prix est attractif, et la livraison Fedex rapide (moins d'une semaine), à partir des Usa, taxes comprises dans les frais de fort.Mes regrets :1) Les capteurs sont internes au boîtier, une sonde externe serait la bienvenue.2) Une prise SMA pour connecter une antenne extérieure serait également intéressante en RFBilan :Pour un prix très attractif, je dispose d'un appareil polyvalent, portable et léger, assez fiable dans sa gamme, et plus complet que ses concurrents (Cornet, Trifield ...). Je recommande cet appareil.

Crazy product with perfect properties in a cheap looking simple box that will change your life. I trust people comparing it to pro ones, so this is easily the best buy. Stable enough with repetitive results. I removed an old wireless phone from outlet completely. I took gsm phone from hands of my 5 years old son, now only watches it with a distance around 70cm. He does what beeps asks him. My wifi modem is already in corridor so safe, otherwise throw it out of pc desk, it is much more harmful than gsm phone even in 1.5metres. Lcd monitor also emits huge EF, more than old hp p1230 crt!. Do you think it is safe to replace a light bulb when you switch it off? Think twice why. I know earth people has forgotten electricity test pen. Simply test it with product if it has any EF in a turned off state that is harmful for you in the night sleep. Then think again why there is electricity passing the off state 1! pole switch. With the product, you will remember and your children will learn basic middle school physics in a very entertaining way. I am using swiss 4.25 uW/cm2 RF max for children. Due to the the small cell tower at the end of street beside children park, I cannot decrese radiation below 3.5uW/cm2 at home, and at balcony it is crazy. Belgium & italy 2.4uW/cm2 is hard to achieve, I already hate city life everyway and now even much more. If you still discard RF etc, then you will need an EMF meter just like this, simply to see if there is any EF source hidden from your sight that may cause an electric shock for children playing here and there. Thank you GQ electronics and Amazon. Best safety product from industry 0 to industry X.

It is a bit over priced and my wife keeps bugging me with the high voltages she finds nearby the sockets but it does the job I bought it for and I am arranging some measures in order to reduce the impact of the cell tower nearby

I bought this meter, as I saw V/m, thinking that that's signal strength (field intensity) for the RF field, but it was for the electrical field. However, i contacted the manufacturer and they updated their firmware to give the power density reading for the RF field (that did not display initially) in nanowatts/cm2 (from which you can calculate field intensity strength in V/m) or microwatts/cm2 or milliwatts/cm2, and it also shows the maximum total power density since the moment you turned on the meter. Shows total power in a band and total power density too. It comes with a rechargeable lithium battery via USB port of your computer, so you don't need to buy new batteries. It has a lot more features out there than most meters under 300, like RF spectrum analyzer where you can see the total power and total power density and dbm for 6 frequency bands, some radio, some microwave region, allowing you to get an idea of what radiation comes out of radio towers and cell phone towers implicated in some cancer and other disease risks studies. This is a very good meter for wi fi range, as i tested it on many devices with wi fi. I even compared it with the trifield analog meter (which is not sensitive in the low range, the needle type of meter), and sometimes got very similar results in the higher range above 50 microwatts. I am not an electrical engineer, so i am not sure how accurate this thing is, or how accurate trifield analog is, but it picks up 2.4 GHz signal from microwave ovens (don't sit near your microwave and keep laptop away from you, since the radiation near wi fi phones and laptops is high, similar to near a microwave oven). If you want a feature to be added or improved, these guys are very eager to do so, as they update the firmware as requested by email, and most manufacturers don't do that. So that's a big plus. I suspect the future versions of this will be much better. The 6 bands for RF are 153-534 KHz, 520-1710 KHz, 2.3-23 MHz, 64-108 MHz, 240-1040 MHz, 2.4-2.5 GHz. The range for the whole spectrum of microwaves is 0.24 to 7 GHz, a wide range now, to be expanded in future versions, per manufacturer, from their emails. This is the meter with the most features i've seen around. The magnetic meter is very accurate i believe, as it matches the trifield analog perfectly many times, the mGauss that the EPA says must be below 2 mGauss when you are 1 foot from the monitor. The electrical field also matches the trifield analog, a popular meter that's been around for 20 years. This meter may become actually very popular, even if now it's not in every online emf store. It has speaker, alarm, allowing you to set it to beep when mGauss, V/m go beyond a certain level. I measured several cars and i was shocked to find that gasoline cars have stronger magnetic fields than electric ones many times (only 1 electric car i could test so far, mine). This meter is better designed to pick up cell phone signal than the 360 version. :) No extra RF and EMF in an electric car, so that's good news. I think the magnetic measurement may be better on this one than the trifield analog. Since many people go sick near cell phone towers, one thing i found is that going inside a building diminishes it and people can use RF blocking paint or aluminum foil to reduce exposure if sensitive. If you are very concerned about RF (radio and microwave frequencies) and want to do a lot of research on these frequencies, perhaps you can buy several meters and see what each does and says the level is at and take it from there - because honestly, i am not a physics expert and don't have several digital meters to compare all readings with. Nice thing here is you can see in the RF graph what frequency a big signal has. This meter may not be perfect for some people from every point of view, may not pick everything up one wants to pick up (every band and every phone brand, etc), but it's educational, and teachers can probably use it to teach about power density, field intensity, electrosmog, RF smog, etc... Hopefully this helped you. :) From watching videos online from wi fi in schools websites it's pretty clear to me that this meter gets about the same values for RF field as the meters in those videos. One video there got 21565 nanowatts/cm2 for near a laptop with wi fi and this is what i get with this one too many times, especially when loading stuff. Wi fi detection, a concern of many teachers and parents, is very good. Wi fi is the 2.4-2.5 GHz band where you see peaks come and go. Sometimes readings are lower than trifield analog for certain cell phone brands, but again, for the price this is a 5 star. Every meter has its pros and cons. the TF2 from trifield.com only shows 2 numbers, while this one can show dozens of numbers, spectra frequencies, etc... Give it a try i guess and if you don't like it, ask questions by email or firmware to be changed or return it. :)

First off, bought the EMF-380v2 by mistake. Meant to purchase the EMC-390 hence have to return it to GC. Tested this model out over the weekend before shipping it back. Can't wait to get the EMC-390 replacement unit.So far this instrument has exceeded any and all expectations. Currently have several professional HP, Rhode & Schwarz, Anritsu, and Advantest RF field survey instruments for comparison. During a few days testing the only negatives that have turned up are, that the Windows software has trouble rendering the waveforms on PCs that are equipped with Nvidia graphics cards, and is generally clunky when changing settings or monitoring the animated graphs over the USB port connection.This particular model lacks case markings that show the internal antenna/sensor orientation, having some would be helpful, as well as, a 1/4-20 camera tripod adapter embedded into the case or maybe a snap around mounting adapter? Just some suggested improvements in usability.As an aside, some form of detector output to a 2.5mm headphone jack would be very helpful for recording base band signals for use with external spectral analysis software, sometimes needed to identify the actual source of the offending emission. Having some sort of audio indications when using the meter standalone would be really handyAll in all, the the EMF-380 exceeds all expectations for an instrument in this price range, and is literally an incredible value. Very pleased with this purchase...Buy one, it works great.

Very sensitive measuring instrument , should have included a Volts per metre in th R.F. section of the meter read out. Handy for checking magnetic and electric fields around the house and what equipment, Microwave -Ovens WI-FI Routers etc and or common appliances emit the most electropollution. The battery lasts a long time which can be re-charged in situ.
