❓ Frequently Asked Questions (FAQ)
Q1: What does the testo 417 measure?
A. 417 measures airflow speed, volume flow and air temperature.
Q2: What’s the difference between the main unit and the kits?
A. The main unit is just the anemometer. Kit 1 adds two measuring funnels. Kit 2 adds the funnels plus a flow straightener for swirl outlets.
Q3: Are the kits good for residential ventilation?
A. Yes. They are designed to make residential ventilation balancing faster and more accurate.
Q4: Do I need the App to use the testo 417?
A. No. The instrument works on its own, but the App makes setup, data storage and reporting much easier.
