And it’s obviously vital to select the right type (or types) of EMF meters for what you want to measure.
So in this review, I will address each type of meter separately.
Key Considerations
Before we get into this, let’s talk about what you should be looking for in a new EMF meter, in terms of features.
When evaluating EMF meters, accuracy is paramount. Now, keep in mind, this article discusses consumer-grade meters. Because these are the types of meters that are affordable and practical for consumers. Obviously, expert-grade meters are going to be more accurate — but they cost thousands of dollars, so I don’t address them here.
A high-quality EMF meter should provide reasonably precise readings of various types of EMF radiation. Additionally, consider the frequency range of the device; a broader range means more types of EMF can be detected, offering a complete assessment of potential risks.
User-friendliness is another critical factor. A good EMF meter should be easy to use, with a clear display and intuitive controls. For those who are not technically inclined, a device that offers straightforward, easy-to-interpret results is preferable. Some advanced meters also come with features like data logging and connectivity options, which can be useful for those who wish to track EMF exposure over time or require detailed analysis for professional purposes.
Power Density Meters
Power density meters are designed to measure the intensity of radiofrequency (RF) radiation. This type of EMF is commonly emitted by wireless communication devices like cell phones, Wi-Fi routers, and broadcast towers. Power density meters assess the power density of RF radiation in an area, which is crucial for understanding exposure levels in environments saturated with wireless technology. Because these meters measure power over a given area, they provide readings in units such as milliwatts per square meter (mW/m²) or microwatts per square meter (µW/m²).

- Tri-Mode Functionality: The most significant feature of the Cornet ED88T is its tri-mode capability, which allows it to measure RF radiation, magnetic fields, and electric fields. This versatility is akin to having three meters in one, providing comprehensive EMF detection.
- Broad Frequency Range and Sensitivity in RF Mode: The meter shines in its RF radiation functionality, boasting a wide frequency range from 100MHz to 8GHz. Coupled with an improved sampling rate of 10,000 samples/sec, it offers excellent sensitivity, making it adept at detecting a variety of RF sources.
- Sound Function for RF Mode: The sound function in RF mode is a distinctive feature that enhances the meter’s usability. This function allows users to hear EMFs, providing an additional layer of information beyond visual readings. It’s especially useful for detecting low levels of EMFs that may not be immediately visible on the display.
- Histogram Function: Another notable feature is the histogram function, displayed on the right side of the LCD screen. It records the last 30 readings since the meter was turned on, which is particularly useful for measuring radiation from smart meters and other devices that emit radiation in short bursts. This feature makes it easier to observe and interpret these intermittent signals.
- Affordability: Despite its extensive range of features and functionalities, the Cornet ED88T is priced competitively. It offers broad functionality, typically found in more expensive EMF meters, at a more accessible price point, making it an excellent value for its capabilities.

Dirty Electricity Meters
Dirty electricity meters, the fourth type, measure electromagnetic interference present on electrical wiring. Dirty electricity refers to the irregular and potentially harmful electrical frequencies that can be generated by certain modern electrical devices and dimmer switches. These meters detect spikes and surges in electrical power lines that are not part of the regular 50/60 Hz electrical frequency. Measuring and mitigating dirty electricity is crucial in environments where there is a high usage of electronic devices, as it can contribute to electromagnetic pollution, potentially impacting health and the performance of sensitive equipment.
Once you’ve taken measurements with these meters, you can then take action to remove or replace the sources of DE or reduce DE levels through plug-in filters or full home filters.
Since these types of meters need to plug into outlets, make sure to get a dirty electricity meter that is designed to work with the power grid where you live.
Satic EMI Line Monitor
$179
The SATIC EMI Line Monitor is a specialized device designed to measure electromagnetic interference, commonly known as ‘dirty electricity’ (DE), in your home or workplace environment. Satic also makes versions for both the North American and the UK power grids.
Some key features include:
- DE Measurement and Visualization: The SATIC EMI Line Monitor effectively measures the levels of dirty electricity present in electrical circuits. It provides both visual and audio feedback, with an LCD display showing a swoosh-shaped line diagram indicating peak interference. The louder the audio feedback, the higher the levels of DE on the line. This real-time feedback is crucial for understanding and managing DE exposure.
- Wide Measurement Range: The device measures interference in millivolts (mV) from peak-to-peak, with a range from 0-2999mV. It records peak mV while also displaying real-time mV, allowing for a comprehensive understanding of DE levels. This wide range is particularly useful for detecting a variety of DE sources within a typical home or office environment.
- Ease of Use and Practicality: The SATIC EMI Line Monitor is designed for simplicity, plugging easily into any electrical outlet. It features an LCD display for easy reading, measures in millivolts, and displays both peak and real-time measurements. The meter is also capable of showing voltage and has an audio indicator for DE levels, making it a practical tool for assessing dirty electricity. Its design also demonstrates the effectiveness of DE filters.
In summary, the SATIC EMI Line Monitor is a valuable tool for anyone looking to measure and manage dirty electricity in their environment. Its ease of use, comprehensive measurement capabilities, and practical feedback mechanisms make it an excellent choice for both personal and professional use in monitoring and mitigating electromagnetic pollution.

TriField Line EMI Meter
$145
The TriField EM100 Power Line Monitor is a specialized device designed to measure electromagnetic interference (EMI) in single-phase AC power lines. Key features include:
- Noise Measurement: It displays total line noise in millivolts peak to peak (mVp-p) with a range of up to 1999.9 mVp-p and a resolution of 0.1 mVp-p. The frequency range for measurement is between 10 KHz and 10 MHz.
- Sound Representation: The EM100 includes a speaker that plays the sound of the EMI, amplitude demodulated. This feature helps in identifying the source of the EMI, whether it’s from a radio station, motor, or electric arc.
- Operating Specifications: The device operates on a voltage range of 85-300 VAC 50/60 Hz and offers a voltage reading accuracy of +/- 1 VAC. It is compact in size (5.2 x 3.6 x 1.6 inches) and lightweight (8 oz), and it comes with a detachable 2-wire power cord rated for 110V in North America.
This monitor is an effective tool for those needing to assess and mitigate EMI in residential or work environments, particularly useful for diagnosing issues with home appliances or electrical wiring.
