Humidity is the hidden reason a home can feel sticky, musty, or clammy even when the temperature looks fine. This guide shows Aussie HVAC techs how to use the Testo 605i wireless thermohygrometer to measure humidity and dew point, explain condensation risk in plain language, and build a cleaner, faster Smart Probes workflow across Brisbane, Sydney, Darwin, and Melbourne conditions.

Moisture is the quiet cause of many call-backs. This guide shows how a Testo vacuum gauge gives you real micron proof, so you stop guessing and start confirming dryness, stability, and leak behaviour. You’ll see the full Testo vacuum range in Australia, how to choose between the 552 and 552i, and the simple rise-test habits that protect your labour on Brisbane, Sydney, Melbourne, Perth, and Darwin jobs.

Sick of chasing shaky readings on split systems? This guide breaks down the Testo 550 series in plain Aussie terms, including the 550s Smart and 550i app-controlled options. You’ll learn when a 2-way manifold is the smarter pick, how wireless workflows save time on Brisbane humidity days and Sydney coastal calls, and when it’s worth stepping up to a 557-style setup. Built for Aussie conditions, focused on faster diagnosis, cleaner reporting, and fewer call-backs.
