 Product Description

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
