EMF Reader
Great product and arrived early.

Piece of junk
This "instrument" would not turn on, would not charge, would not do anything. The "manual" was a tiny paper with no help. I sent it back immediately. Amazon charged me a dollar to send it back by UPS vs Kohls or Whole Foods, which are an hour away.

Reasonably priced EMF meter!
Love that includes all 3 types of EMFS to measure. Super easy to use and more affordable than other options that do the same. You might be shocked to see how many EMFS some of your devices are putting off!

This is an interesting meter for measuring a wide range of electromagnetic energy.
The media could not be loaded. The meter has a large, easy to read, illuminated, LCD display and a sturdy case that is easy to hold, it is rechargeable and comes with a short USB-A to USB-C charging cable. An extremely basic instruction manual is included as well. The instructions point out, to get consistent readings, it is important to hold the meter from the back, which I did when using it.The meter has 6 modes, selectable by dedicated buttons on the control panel:- ELEC - measures "Electrical field intensity", this is used to measure the "Electro" part of the electromagnetic (EM) radiation emitted by electrical wires and equipment from 40Hz to 100Hz. Here in North America, the electrical system is based on 60Hz - AC. When the meter is placed next to an electrical outlet or switch you would expect the frequency scale on the display to indicate 60Hz. I found this not to be the case. The frequency scale seems to be showing a graphical representation of the V/m measurement, which is not directly related to the frequency of the EM field. Also the readings were wildly inconsistent and seem too high, for example, it read between 600Vm and 999Vm when placed 1mm away from a household light switch. It seems unlikely the light switch is leaking 600 volts per meter - 600 millivolts (mV/m) seems more likely.- MAG - this measures the "Magnetic" part of any electromagnetic energy present in milligauss, which is 1/1000th of a gauss. This is possibly a more useful measurement if you are concerned about EMF exposure. Multiple mG readings of the same light switch at 1mm away were between 0mG and 0.4 mG, again, with inconsistent readings from exactly the same spot and distance from the switch. I also took multiple readings 12 inches away from a microwave oven set at high power for 10 seconds, using the MAX function on the meter, as microwaves use pulses of energy. Over multiple tries the meter provided readings from a low of 36.4mG to over the max of 99.9mGRF - this measures Radio Frequency energy between 20MHz and 6GHz in mW/m2 (milliWatts per square meter). US government guidelines consider exposure under 0.0001 of "no concern", with exposures between 0.0001 - 0.01 of "slight concern" and anything above 0.01 of "severe concern". I took multiple readings 12 inches away from a microwave oven set at full power to 10 seconds, using the PEAK function, as microwaves use pulses of energy. The meter again provided inconsistent readings from 3.9 mW/m2 to over 6.4mW/m2 . The light switch measured at 1mm from the switch provided readings from 2.9 to 4.1 mW/m2. The meter did not provide any reading of our WiFi until it was placed within a few inches of the router.There are two other buttons on the meter: W-ELEC and W-MAG, which provide "weighted" measurements, I did not find these provided any more consistency than the "standard" measurements offered by the other buttons. The last button selects MAX or PEAK depending on the mode. This is helpful for measuring energy source that pulse or are transient.Conclusion:This is an interesting device, that in my use, provided inconsistent readings in all modes.I expect variability in the readings, however, the variability of the measurements exceeded what I consider acceptable for my reliance on a meter. That said, this does provide a means of showing how much EM radiation there is in everyday environments and devices. It would be nice if there was a way to verify the calibration of the device.My main take-away from my initial use is, I have to do additional testing to make sure I am using it correctly, and to see if I can get more stable readings. I will update this review if my findings improve.

EMF and sleep distirbances
When your health matters, the more features allowed us to thoughtfully reconsider where the placement of electronics within our sleeping areas. This unit detects radio waves, temperature (draft and circulation)and wi-fi issues.

My meter was defective right out of the box.
Ok, I'm sure that some defects get passed QC inspection with any manufacturer. But, in this case I am glad it came to me malfunctioning because I returned this item and ordered a GQ EMF-390 meter instead.The Olmlmo meter had six functions and five worked okay for me. The weighted EMF function was unable to return to lower readings after being exposed to magnetic fields over 90 mG. I had to turn the meter off to reset that mode. Very irritating!So, this is two reviews in one. The GQ meter costs a few dollars more, but it's worth a dozen Olmlmo meters. The Olmlmo can display only one type of field at a time. The GQ displays electric field, magnetic field, and RF field simultaneously on the screen. It also analyzes the RF as to both type and specific frequencies. It's actually an amazing meter. It takes some time to understand the advanced features it has, but the basic (highly useful) functions are super easy to use and quite enough for the average person, I'd say.This type of review is not my usual style, but I wanted to clue some folks in on the huge difference between these two meters.The Olmlmo has one feature I like, the weighted modes. Still, I say the GQ is far more useful and valuable. Sorry Olmlmo... Thanks, but no thanks.

I got this for ghost hunting and I love it.
I'm pretty sure that I have a ghost at my job. We joke that it's the Holy Spirit, as I work at a church, but seriously, there's some weird noises, tapping, hissing, all over the place. And yes, I've had the gas lines and electrical systems checked. Things move on their own and sometimes there's a lot of noise in unoccupied rooms, enough that the noise will trigger the hall cameras in the middle of the day/night, and I'll go back and check the footage when I see the alerts, to hear noises that I didn't hear happening right outside my office door while I was there. Really weird.I'm fine with the Lord's hand at work, but I wanted to see if I could catch some EMF signal while the weirdness is going on. So far, the ghost has been quiet on the days that I've taken this to work. I forgot this today and the rattling and clattering was wild for about five hours on and off, and no one else was in the building! So, it knows.Easy to use right out of the box. It has a USB-C charging port and cable included. If I lose this cord, no big. I've got a ton of USB-C chargers lying around.There are a bunch of different modes, and I don't understand them all, but they're pretty cool to flip between and see what registers. I'll have to do my research on what they really mean.My son loves playing with this. He's a huge Ghost Adventures fan, so he's already planning his podcast episodes that will feature this, lol. I'm more into Ghost Hunters, but to each their own. My husband understands all the modes and plays with this sometimes. While it's pretty sensitive and picks up on a lot of signals, it does not pick up on our wireless cameras. Phones, yes, however, which is good to know.I really hope to catch some activity at work next week. I just have to remember to bring this!

Very disappointed
Disappointed. I really bought this for the RF reading and it gives you zero!!The EMF seems to work just fine but my outdoor meter gives off no RF? Ha! My cell phone, tablet?I missed the return date or it would go back!
