STA2 – Anemometer Hot Wire

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.
