The Fieldpiece STA2 In-Duct Hot-wire Anemometer is a Hot-wire Anemometer built for the HVACR professionals' air balancing needs. The compact probe tip of the Fieldpiece STA2 makes measuring air velocity directly in the duct a breeze. The Fieldpiece STA2 is 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.

As the newest addition to the family of test tools HVACR professionals trust to do more, the Fieldpiece STA2 In-Duct Hot Wire Anemometer is a great alternative to costly bulky hoods. With ease, techs can input free area, and the Fieldpiece STA2 automatically averages multiple test points and continually calculates and displays CFM.
