Ditch the hood.

In-duct air balancing with fast response time
Minimizes turbulence effect
Hands free testing
38″ telescoping probe in in-duct traversing
Dual display shows combo of real-time CFM, air velocity, or temp


The STA2 is a Hot-wire Anemometer built for the HVACR professionals’ air balancing needs.  The compact probe tip makes measuring air velocity directly in the duct a breeze.  It’s great for traversing a duct and automatically calculating CFM without the hassle and expense of a bulky hood.  The 38″ telescoping probe’s laser etched ruling and flattened edges allows techs to locate proper measurement points within a duct, and ensures that the probe is properly aligned.


This in duct hot-wire anemometer quickly calculates CFM from air velocity and free area.  And with the intuitive interface, the STA2 makes it easy to capture the correct data.
