Covering a wide frequency range from 5 kHz to 10 MHz, it provides instant millivolt readings via a digital display and audio feedback, enabling users to locate pollution hotspots, evaluate electronics' impact, and optimize filter installations. Trusted by thousands, it empowers professionals and homeowners alike to reduce invisible electrical noise for healthier, more efficient environments. ## Description Dirty electricity—also called electrical noise, line noise, or power line EMI—is unwanted high-frequency electrical energy that travels along building wiring along with standard 50/60-Hz AC electricity. Electronics, appliances, energy-efficient lighting, dimmers, chargers, solar power inverters, and many other modern electrical devices can produce dirty electricity as they operate. Dirty electricity can also enter a building through incoming power lines. Once on the wiring, it can spread throughout a building and radiate into surrounding living and work spaces. The Greenwave EMI Meter is designed specifically to measure this high-frequency electrical pollution on building wiring. It measures a broad range of dirty electricity frequencies—approximately 5 kHz to 10,000 kHz (10 MHz)—and provides measurements in millivolts (mV). Because dirty electricity can vary from outlet to outlet and change as electrical devices operate, measuring helps you better understand what’s happening in your own electrical environment. The meter lets you observe how devices affect dirty electricity on the wiring and evaluate whether steps you take to reduce this electrical pollution are effective. For those using dirty electricity filters, measurements provide a more customized and informed approach to installation. Rather than relying solely on general recommendations, you can use actual readings to guide filter placement, compare results as filters are added, and determine when additional filters are no longer providing meaningful improvement. This measurement-guided approach can help you optimize filter installation. Dirty electricity levels are displayed on the meter’s digital screen, while the audio feature lets you hear changes in those levels as sources are turned on or off and filters are installed. BEFORE and AFTER readings can also be viewed simultaneously for easy comparison. Review: Impressive precision—a must-have for serious system optimization - I was very skeptical about this device initially, but it absolutely works. Having experimented with many different power filtration methods—ranging from simple capacitive filters to heavy custom common-mode chokes (CMCs)—I wanted a reliable way to measure the actual impact. The precision of this meter is quite impressive across a very wide band of frequencies. While it is on the pricier side, it is entirely worth the investment if you are serious about diagnosing and bringing down the EMI floor in your home theater or stereo system. Review: It works . - If I had not purchased this item, I would not know that we were receiving a radio channel through the plug-in next to our bed. It is very accurate and a good value for the money displays easily and is very easy for someone to use. You has no previous experience with electricity. I bought this for an annoying high-pitched noise and found a baseball game playing through the plug-in. This item definitely works and was very helpful in showing the Electrician what was wrong! It also shows when there’s too much dirty electricity coming out of which sockets if you compare all the sockets in your home and tells you what is too high. It was a good purchase for me. ## Features - DISCOVER THE INVISIBLE POLLUTION ON YOUR WIRING: Measure dirty electricity—high-frequency electrical pollution that flows along building wiring and radiates into living and work spaces. Simply plug the EMI meter into outlets for instant readings. - FIND DIRTY ELECTRICITY HOTSPOTS & SOURCES: Check outlets in your environment to find where dirty electricity is highest and investigate electronics, appliances, lighting, and other devices that may be creating dirty electricity on your wiring. - GUIDE DIRTY ELECTRICITY REDUCTION: Use actual measurements to guide your efforts to reduce dirty electricity—from identifying and reducing sources to optimizing dirty electricity filter installation. - SEE THE DIFFERENCE YOUR CHANGES MAKE: Establish baseline readings, take steps to reduce dirty electricity, and measure again. Before-and-after readings let you see how effectively your changes are reducing dirty electricity. - SEE IT—AND HEAR IT: View dirty electricity levels in millivolts (mV) on the digital display. The audio feature lets you hear levels increase when dirty electricity sources are turned on and decrease as you install filters or remove sources. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01MEFVYQD | | Best Sellers Rank | #58,743 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #32 in EMF Meters | | Brand | Greenwave | | Brand Name | Greenwave | | Color | Black, white | | Customer Reviews | 4.5 out of 5 stars 150 Reviews | | Item Dimensions | 5 x 4 x 3 inches | | Item Highlight | Precision Plug-In Dirty Electricity Meter – Accurate Voltage Measurements – Trusted by Thousands of Customers | | Item Weight | 8 ounces | | Item dimensions L x W x H | 5 x 4 x 3 inches | | Manufacturer | Greenwave International, Inc. | | Measurement Type | Voltmeter | | Model | Broadband EMI Meter | | Number of Items | 1 | | Power Source | Corded Electric | | Specification Met | RoHS, UL | | Style | Electronic | | Style Name | Electronic | | UPC | 700987683257 | ## Product Details - **Brand:** Greenwave - **Color:** Black, white - **Item Weight:** 8 ounces - **Power Source:** Corded Electric - **Style:** Electronic ## Images ![Greenwave Broadband EMI Meter | Calibrated Dirty Electricity Meter - Image 1](https://m.media-amazon.com/images/I/41DxWwTs52L.jpg) ![Greenwave Broadband EMI Meter | Calibrated Dirty Electricity Meter - Image 2](https://m.media-amazon.com/images/I/31Yi4EibpmL.jpg) ## Questions & Answers **Q: Will plugging in a filter reduce the readings on other outlets on the same circuit, and/or on other circuits?** A: Yes and this is why the meter is valuable. I have plugged the filter in different locations to test for the best suppression. **Q: Can i use my trifield 100xe instead of this?** A: No. You need a plug in meter. Like the Greenwave meter or an Oscilloscope thx! **Q: Why do I need this device, if all it does is measure dirty electricity?** A: This meter is necessary to determine if you have dirty electricity in your home. Per Greenwave, if this meter measures over 50mv (to me 50mv is acceptable) it is considered to be dirty electricity putting out fields that are unhealthy. If you detect dirty electricity, then you purchase the filters from Greenwave. We had excessive dirty E when measured. Some rooms measured over 600mv. Keep in mind the measurements can vary throughout the day (and appliances operating). We measured one outlet in the bedroom that was approx 600mv, when we plugged in the filter and measured the outlet above it, it dropped below 50mv. Since we now have 2 filters in the bedroom and in other rooms, we are now sleeping better than ever - yes the dirty electricity was indeed interfering with our sleep and thus we are feeling better during waking hours. I hope this helps. **Q: Is there an adapter to be able to check 220V lines i.e. furnace, dryer, water heater?** A: There is a way to do it...but you will have to ignore some electrical safety protocols. A 220 line is simply two 110 lines. Open up the receptacle and use jumpers from one hot line (110) and attach other jumper to ground. Then repeat for the other 110 line. Warning...live electricity...need I say more...careful. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Impressive precision—a must-have for serious system optimization *by N***L on June 8, 2026* I was very skeptical about this device initially, but it absolutely works.
