Choosing tools for Australia’s OPSGG/ARCtick landscape? This guide shows how to connect Testo 557 Bluetooth, use the vacuum probe and micron gauge, pull a deep vacuum, and export logs that satisfy building managers and regulators. We compare Testo 557 vs Fieldpiece SM480V, outline refrigerant/threads compatibility, and share calibration/maintenance tips for Aussie conditions—from Perth rooftops to Brisbane plant rooms.

Stop losing time to disputes and rejected claims. The Testo 557 turns every evacuation into insurance-ready proof: pair via Bluetooth, use the external Pirani (0638 1557) for honest microns, pull a deep vacuum with large-bore hoses and core tools, isolate for a rise test, then export PDF/CSV with photos straight from site. Attach those logs with your RHL/RTA and calibration certificates to meet ARCtick expectations and align with Australia’s HFC phase-down goals. Built for Melbourne’s four-seasons and Brisbane humidity, this guide covers the step-by-step workflow, calibration and probe care, compatibility notes (R32/R410A/R22; 1/4″ vs 5/16″), and when to upgrade. We also compare Fieldpiece SM480V for long line-of-sight monitoring and a 3/8″ vac port on big plant, while showing why the 557’s sensitive readings and app reporting shine for proof-first evacuations.
