Airflow “feel” isn’t a number. This guide breaks down anemometer vs balometer (capture hood) in plain tradie terms—what each tool measures, what affects accuracy on real sites, and when each makes sense for Aussie ducted and light commercial work.
Temperature measurements stop guesswork on split systems. This guide shows a simple, repeatable workflow for return and supply air checks, correct pipe clamp placement on suction and liquid lines, and how to avoid false readings caused by poor contact, sun, wind, and mixed air. You’ll also learn when Type-K thermometers, wireless clamps, and data loggers make troubleshooting faster and records more reliable on real Australian service calls.
