Description

Fieldpiece STA2 Anemometer Hot Wire

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. Its great for traversing a duct and automatically calculating CFM without the hassle and expense of a bulky hood. The 38 telescoping probes 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.
