Amazon hat sich um Zoll usw. gekümmert. Der Preis war wie beschrieben, keine extra Kosten. Die Bedienungsanleitung ist auf Englisch. Habe gleich einen kurzen Test mit meiner Vakuumpumpe durchgeführt. Dazu haben ich mir die Testo Smart App heruntergeladen. Die ist intuitiv bedienbar und stellt die Messwerte auch graphisch dar. ## Frequently Bought Together - testo 552 - Digital Vacuum Gauge (Bluetooth) - 2PCS Filling Refrigerant Safety Valve Quick Coupler Air Conditioning R410A R22 Connector Adapters --- ## 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.pl/products/259188724-552-digital-vacuum-gauge-with-bluetooth-communication](https://www.desertcart.pl/products/259188724-552-digital-vacuum-gauge-with-bluetooth-communication) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-27*
