As a electrician and refrigeration technician is fills all the gaps other testers don't. Greatest point is the size of clamp for amperage, you can usually get it snuck in areas others don't on 3/0 and little bigger. Price is great to. I have Fluke meters, but this is preferred tester. ## Frequently Bought Together - UEi DL389B Digital True RMS Clamp Meter, HVAC 4000 Counts Auto Ranging Voltmeter, Measures AC & DC Volts AC Amps AC/DC Microamps Temperature Frequency Resistance Capacitance Duty Cycle NCV Diode Test - UEi Test Instruments ATTPC3 Pipe Clamp K-Type Thermocouple adapter, HVAC Temperature Probe for Clamp Meters, Surface Thermometer for Boiler and AC Line Temperature Readings - UEi Test Instruments PDT650 Folding Pocket Digital Thermometer,Yellow --- ## 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.hr/products/179495396-uei-test-instruments-dl389b-true-rms-dual-display-clamp-meter](https://www.desertcart.hr/products/179495396-uei-test-instruments-dl389b-true-rms-dual-display-clamp-meter) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-14*
