Works Great *by D***C on September 15, 2025* As Described. Works Great. Chasing down electrical gremlins is always a fun time ### ⭐⭐⭐⭐⭐ ✅ easy to use, helps identify noisy circuits *by O***N on January 23, 2022* I bought this product while looking to improve the powerline noise situation in my home office. I have many electronic devices powered from the same line - computers, monitors, chargers - that spew noise back and negatively affect the audio quality of desktop DACs and headphone AMPs. I found Trifield EM100 to be an equally helpful tool in measuring the line noise level and discerning between various available filter products. I wish it had a button or switch to turn OFF its speaker for those of us who keep it plugged in 24/7. Other than that, I see absolutely nothing wrong with it. ## Frequently Bought Together - Dirty Electricity Meter by Trifield - Model EM100 - EMI Power Line Noise Analyzer - Know Your Electricity @ Home, Office, Shop - Made in USA by Alphalab, Inc. - TriField EMF Meter Model TF2 – #1 Handheld EMF Detector for 3 Types of Electromagnetic Fields: Radio (RF), Magnetic (MF) and Electric (EF) - Measure 5G, Cell Towers, WiFi, Bluetooth, & Smart Meters - Greenwave Dirty Electricity Filters: Mobile Travel Kit (2 Filters) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/185036809-dirty-electricity-meter-by-trifield-model-em100-emi-power-line](https://www.desertcart.pt/products/185036809-dirty-electricity-meter-by-trifield-model-em100-emi-power-line) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-08-29*
