The probs only measure line temps. I have the wireless versions and the kit comes with the micron sensor **Q: do this kit has hoses?** A: No. Hoses are separate. ## Frequently Bought Together - testo 550s AC Manifold Gauge Set – Manifold Gauges Hvac and Refrigeration – Incl. 2x testo 115i Pipe Clamp Thermometer, 1x testo 552i Micron Gauge Hvac - AC Recharge Kit with Bluetooth - Appion MGAVCT 1/4" MegaFlow Vacuum-Rated Valve Core Removal Tool - Hvac Service Wrench Tools:3/16” to 3/8” 5/16'' x 1/4''Air Conditioner Valve Ratchet Wrench with 2 Hexagon Bit Adapter Kit for Air Refrigeration and Equipment Repair Tools Clearance --- ## 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.us/products/695576592-testo-550s-kit-i-app-operated-digital-manifold-set-2](https://www.desertcart.us/products/695576592-testo-550s-kit-i-app-operated-digital-manifold-set-2) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-10*
