Fieldpiece STA2 In Duct CFM Hot-Wire Anemometer

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.

Features:

• Measures air velocity and temperature
• Calculates CFM
• Slim 38" telescoping probe for in duct traversing
• Fast response time
• Dual display for combo of real-time CFM, air velocity, or temp
• Depth and direction indicators
• Minimizes turbulence effect with time/test point averages
• Hands-free testing with stabilizing cone and magnetic hanger
