EMF Meter: Tri-mode ENV RD-10

Weighing less than 50 grams, this is the most compact, powerful yet affordable three-mode EMF meter available today.   With a high frequency RF range, this 5G-ready, 3-in-1 pocket-size meter measures the main EMFs in our living environment: Radio waves, Magnetic fields and Electric fields.

Super easy to use, this meter shows EMF field strength with 9 LEDs (green, yellow, red).  On/Off audible alarm beeps to signal a high EMF zone.  Built-in rechargeable battery is good for 8-10 hours per charge. Connects to laptop or mobile device to log precise EMF readings (free software can be downloaded).

Light as a feather, keep it anywhere: purse, pocket, wallet, dashboard, glove box or on the nightstand; take it everywhere: home, office or other workplace, car, school, hotel, vacation.

 3-in-1 EMF Meter ✔ 5G-Ready ✔ Super Easy to Use
✔ Compact ✔ Lightweight ✔ Highly Sensitive
✔  Best Value ✔ EMF Data Logging

The world’s most compact, easy to use, best value, 3-in-1 EMF meter.

This EMF detector is designed for non-professionals. Extremely easy to use, compact, lightweight and highly affordable, it has high sensitivity for its price range.  

With this unit, you can easily scan each environment you’re in for EMF safety levels.  

Its super-sensitive RF alarm mode will allow you to walk around with the meter for hours. When the audible alarm mode is turned ON, the meter will alert you, with beep sound, whenever you are in a high RF environment or close to an RF source like mobile cell towers.

Like many of the more expensive EMF meters, its high-frequency range is extremely good: 100MHz to 8GHz.  This means that it will even pick up the lower band of the 5G spectrum.  

It has a very fast sampling rate (20,000 / second), enabling it to pick up even the fastest RF signals. 

It measures radio waves from cell towers, smart meters, Wi-Fi routers, Bluetooth devices, cordless phones, cell phones and microwave ovens. 

It measures Electromagnetic fields from power lines, fuse boxes and home appliances. This will give you a picture of the EMF radiation you're exposed to.

Additionally, you can connect the unit to a laptop or Android phone for more sophisticated features: real-time data viewing, logging and recording of the EMF readings over a period of time.  


Relatively inexpensive product that is quite accurate to test EMF exposure! - Leasmill


For the purpose of simply knowing at a quick glance if you're being exposed to dangerous levels of EMF, this is phenomenal. … Good alarm feature. Personally I like to have the alarm feature ON so that when it beeps, that opens the door to a conversation with others and hopefully the chance to educate them about EMFs. I take this everywhere and love it! -Valeri 

Just get it!
Replaces all my other meters (besides dirty electricity). Very portable and accurate. It may save your (or your loved ones) life!! Shows you dangerous levels of radio, magnetic and electric fields. - A***W

Frequently Asked Questions

How does this EMF meter compare to other EMF meters in the market today?
Here is how independent EMF experts have rated ENV RD-10:

In his book, EMF*D (pp 235-236), Dr. Joseph Mercola writes:

It is much smaller than any similar meters on the market.

It offers good sensitivity for the price, and compares very well with other more expensive meters (Acousticom2, Cornet ED88TPlus, and Trifield TF2).

RadiationHealthRisks.com’s David lists ENV RD-10 as the #1 EMF Meter in his blog: 9 Best EMF Meters and Detectors - My Top Picks

This is a brand new meter to me that I have only recently tried for the first time. I really like it. So much so that I am listing it as number one on this list.

Tips to get started with the device
It is recommended to fully charge the device before using it for the very first time.  A full charge should give it 8-10 hours of operation.
Can the device be used without being connected to a PC or mobile phone?
  • Yes, this EMF meter is a superb detector on its own.
  • You can connect it to a PC, Mac or mobile phone to capture precise, numerical EMF readings and additional advanced features described below.
What advanced features are available?
Advanced features include: view real-time values and histograms, record data over time, save / export data to spreadsheets for advanced analysis.

Does the histogram feature provide the power spectrum?

Yes, the histogram shows the power detected in the time domain.
What software is needed to use the advanced features?
Free downloadable software works on Windows 7 and above, Windows XP and above, MAC monitor software, Android App works on most devices with version 4.3 and above.

The free software can be downloaded from the manufacturer’s website here. This software can be used to record and view readings from the EMF meter.  The EMF meter is connected to the PC, laptop or Android phone using the supplied mini-USB cable. The User Guide can be downloaded here. The Android version is really cool.  A video showing how to set up and use the Android version can be viewed here.
Is this a single-axis or 3-axis meter?
This is a single axis Gauss meter.  This means that you have to hold it in all three positions (X, Y and Z axes) wherever you are measuring to find the highest value. Otherwise, you may miss the true magnetic field reading.  However, once you get the hang of using a single-axis Gauss meter, it is just as useful as a three-axis Gauss meter.
Does this EMF meter detect 5G?
The 5G cellular network will consist of different modules. It is evolving and currently operate at:

- around 700 MHz

- around 2 GHz

- around 3 to 4 GHz

These are called the 5G low and mid bands. Eventually, higher frequencies (above 20GHz) are planned to be used as well, but there are still technological difficulties using them at present, and will probably take a few more years before they will be implemented and rolled out.

The ENV RD-10 covers the currently used low and mid bands of the 5G network as part of its measuring range.

There are no affordable (<$1000 USD) EMF meters in the market today that can measure 5G millimeter wave signals in the band above 20 GHz. 

The ENV RD-10 adequately detects 4G LTE RF signal from a small cell antenna with a 4G transmitter.  New 5G signals from any updated 4G LTE small cell transmitter below 8 GHZ will be picked up by the ENV RD-10.
Is this EMF meter calibrated?
Yes, each EMF meter is calibrated separately as part of the manufacturing process.

Customer Reviews

Based on 3 reviews

Easy to use. Not sophisticated enough to know details. Does not show numerical values. In high readings it is very crucial. The highest reading covers everything from quite high to infinity. Good for quick research. Useless for real analyzing very dangerous zones.

Vinh Tran
Great meter and great service

The meter works great and is VERY easy to use. Furthermore, Jocelyn was very prompt in getting my order out quickly even though I live in the US. I would highly recommend this product and retailer.

Kevin M
Great tri-band meter!

Great meter - the best you can get for the price (don't waste your money on something cheaper). It's a tri-band and can connect to your computer / phone and works with GPS on your device - this allows for driving around and finding the cell towers in your neighborhood.

I highly approve!
