4 in 1 Emf Meter Emf Detector: Electric Field, Radio Frequency Field Temperature,Magnetic Field Strength Meter, Rechargeable Radiation Detector for 5g Cell Tower,WiFi Signal and Ghost Hunting

We've been using this like crazy it works great and is quick

This is the most sensitive detector of EM radiation that I have encountered, it also performs well at magnetic fields but the electric field detection is where it shines. The range could be greater and that would really set this apart from others but if you need to sense beyond 200 V/m there are other meters you can choose anyways that will likely not be able to do what this one does.RF meters are pretty standard, and this one performs better than most but also does the job I expect it to do. Same goes for magnetics, as long as the field is changing this will detect and estimate the strength, up to 200mG. It also allows for a weighted measurement which, in some cases, has provided a better measurement.The standout feature is its electric field measurement. I can use this for so many things! For example, with power flowing through an outlet or light switch I can determine precisely which way the wires go in the walls. This saves alot of time for me when it comes to remodeling my home. I can also find precisely where a break in a wire occurs. Nearly all of these benefits can be attributed to the sensitivity of the device which is impressive.If you are in need of making good measurements of E fields, B fields, or RF emissions...this meter will help you find whatever is there. Five stars!

I didn't really have a use for an EMF meter, but I have a Flipper Zero and a bunch of objects that are RF controlled around my house. I wanted to test the signals and also see if I could replicate some of them. This meter was fun to play around with and has lots of features. I would classify this as a medium to high tier product instead of gimmicky or junk. Your needs may vary, but this was perfect for my uses!

Don't buy this

Got this on a whim and not sure of the usefulness of such a device but it seems to work. Went around the house checking the magnetic and electric fields of different appliances and the meter spikes when held close to electronic devices. The RF meter beeps like crazy. Gonna try using it for ghost hunting. The temperature reads way too high, the sensor is probably located inside the unit and is picking up the heat of the device.

got this to test for some interference around the house and boy is this sensitive. Not a bad think but it will go off when it picks up a field. I'm far from an expert, but from my uses it has done a great job for my needs

I didn't have a particular use for one, though I have a few ideas where this will come in handy, so I thought I would give the Upgraded-4 in 1 Emf Meter a look. I am glad I did as it has some very good functionality. As another user said, the EM detector is sensitive enough to trace power wires in walls.The case is well made from hard plastic and overall the build quality is good. The screen is good quality and very sharp and clear and makes seeing the results very easy.The RF detector works great and is sensitive enough to detect the Wi-Fi pods, I have throughout my house, from several feet away. The Magnetic field detector is pretty sensitive as well. The Temperature sensor seems to be pretty accurate though I haven't tested it in really cold or really hot conditions yet. So far, the Upgraded-4 in 1 Emf Meter does exactly what is says it does. and I can recommend it!

When it comes to EMF meters, many feel that it's worth owning to measure AC electromagnetic fields, Earth's geomagnetic field, but also for radiation levels and yes, people also use them for ghost hunting.But power lines, TV sets, computer monitors and video machinery give off EMF and for some people, low levels of exposure to EMF can lead to headaches, worsening mental health, nausea, fatigue.So, I was looking for an EMF meter and found one that is about $90, a bit pricey but there is a reason. The meter has multi-functions.For one, aside from EMF reading, it has a temperature testing meter, electric field testing, magnetic field testing, radio frequency testing and what makes it even better, it's rechargeable.Many meters I have require many batteries and this is the first meter which I used that is rechargeable.Last but not least, you get the charging cable, a case and instructions.But overall, I love meters that are multi-function and even better that they are rechargeable. But for those concerned about radiation, this Upgraded-4 in 1 Emf Meter Emf Detector, Electric Field, Radio Frequency Field Temperature, Magnetic Field Strength Meter, Rechargeable Radiation Detector is recommended!
