Klein had great reviews so I gave it a shot when I needed something to diagnose my AC unit. Seems well built, has all the features I need and then some. Hard to beat for the price an comes with a nice storage pouch and thorough instructions. ### ⭐⭐⭐⭐⭐ Great for home use *by on Reviewed in the United States September 22, 2025* So far, this is a great tool. Does what I need it to do for a good price. I use mainly for household work, however. ### ⭐⭐⭐⭐⭐ Another excellent Klein product. *by on Reviewed in the United States July 19, 2025* I have been using this meter for a few weeks now. All I have to say is wow. Very accurate meter. I have compared it to more expensive meters. This meter is right up there with the best. Very fast response accurate readings. I have used Klein tools for years, I’m 73 now. Never had a problem. Nothing bad to say about the quality. Truly excellent. I have a tool cabinet full of Klein Tools.. ## Frequently Bought Together - Klein Tools CL445 HVAC Clamp Meter, Auto-Ranging TRMS, NCVT, Measures Voltage, Current, Temperature, Micro Amps, InRush and More - Klein Tools 69417 Rare-Earth Magnetic Hanger, with Strap - Klein Tools 69409 Line Splitter for Clamp Meter, Measures up to 15A Current Draw, 10x Measurement, Designed for North American Outlets --- ## 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/495784536-klein-tools-cl445-hvac-clamp-meter-auto-ranging-trms-ncvt](https://www.desertcart.pt/products/495784536-klein-tools-cl445-hvac-clamp-meter-auto-ranging-trms-ncvt) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-20*
