If you’re looking for an EMF meter that quickly and easily measures magnetic and electrical fields without too much else, the Meterk EMF meter may be a decent choice. Get the full review after the jump.
Meterk EMF Meter Description
The Meterk EMF meter is a single-axis gadget used to detect common electrical and magnetic fields in your home. The device also measures temperature in °C and °F. It’s not intended for ghost hunting, but like that’s stopped us before, eh?
It’s a lightweight device that has a LED screen to show different readings. The gadget also has 3 different measuring modes (Maximum, Minimum and Average) you can use to detect ranges. However, the meter doesn’t record these settings.
There’s also an alert I’ll discuss toward the end of the review.
Factors Used For This Review
For this test, I focused on usability and accuracy. Then, I compared it to other EMF meters. Let’s begin with usability.
In this case, I wanted to understand ease-of-use without reading the technical documentation. Most people will head out to the field and flip a switch, expecting the gadget to work.
The Meterk users will have to change some settings. First, most ghost hunters use milliGaus for EMF readings, but the Meterk defaults to Tesla. That’s not something most investigators use. One would think you’d simply press the Set button and change it.
That’s not correct. You have to press the Unit key down to switch the Tesla to milliGaus.
Next, the electrical measurement and temperature are on the same display line. By default, the gadget shows electrical first. To show temperature, you hold the Unit key down for a couple of seconds, then use Unit again to change from °C to °F.
After that, the gadget’s simple to use, but it’s not the most intuitive setup.
For the display, it’s pretty straightforward, but you’ll need to read the documentation to get the Maximum, Minimum and Average EMF readings. I skipped it because I wanted real-time measurement.
The display backlight isn’t that intuitive either. To turn it on, you have to press the Set button for a few seconds. Then, 2 small lights come on, but they blur the electrical/temperature readings somewhat.
Next, I tested the Meterk against the EDI+, MEL 8704-R and K2 meter. This isn’t a direct comparison because the Meterk has separate readings for electric fields and magnetic fields. I used magnetic on the Meterk to compare against the others.
The Meterk did measure in line with the other meters. I used my router because it has a consistent reading for EMF. That would be 7.4mG (average over 1-minute and held 3″ above the center).
The gadget comparison readings:
- Meterk: 7.7mG
- EDI+: 7.1mG
- MEL 8704-R: 7.3mG
- K2 meter: Orange (10+mG)
I’d say that falls inline with an acceptable range. Though, the K2 was a bust.
With the temperature, I measured the first floor of my house which averaged 67°F. All gadgets, excluding the K2, measured within ±0.2°F.
The Meterk comes with 2 alerts based on changes in the magnetic field and electrical field. As seen in the video, the meter will sound an alarm and flash red. It triggers at 4mG for magnetic readings and at 40 V/m for electrical. You can change these under the Set button.
I found the electrical default to be too low and it triggered often. As for the magnetic setting, 4mG was a good threshold by default. Temperature does not set off the alarm.
Ghostly Activities’ Recommendation
It’s not too shabby. You get a digital display that measures EMF fields to the tenth of a mG; electrical field measurement (AC only); and a temperature gauge. Plus, it has an alert to direct your attention when it finds something interesting.
It’s best suited for a walkthrough or initial investigation. Once you’ve established that, I’d use a more refined EMF meter like a Trifield Natural EMF meter or a MEL 8704-R-REM-ATDD.
Now, it’s a single-axis device, so you have to move it around to get an average magnetic field output. That’s not so bad, but you have to go through the Mode button to select that. But the device measures quickly and it’s accurate.
For the price ($35-$45 on Amazon), I think you get a useful EMF meter that’s better than a K2 … and less expensive, too.
Note: Jake bought the gadget with his own money, so there’s not expectation of a good review by the manufacturer.
