Fieldpiece STA2 In-Duct Hot Wire Anemometer

The Fieldpiece STA2 measures air velocity directly inside a duct using a compact hot-wire probe tip, avoiding bulky balancing hoods. A 38" telescoping probe, stabilizing cone and magnetic hanger let techs take hands-free CFM readings for air balancing work.

Key Features

• In-duct air velocity measurement — no hood required
• Automatic CFM calculation from air velocity and duct area
• 38" telescoping probe with laser-etched ruler and flattened alignment edges
• Dual display for CFM, air velocity or temperature combinations
• Depth and direction indicators
• Turbulence minimisation via time/test-point averaging
• Hands-free operation via stabilizing cone and magnetic hanger

Specifications

• Air velocity range: 40–3,960 fpm (0.20–20.00 m/s)
• Air velocity accuracy: ±5% of reading or ±1% of full scale
• Air velocity resolution: 1 fpm (0.01 m/s)
• Units: fpm, m/s, km/hr, mph
• Temperature range: -20°C to 60°C (-4°F to 140°F)
• Temperature accuracy: ±1.0°F (32–113°F); ±2.0°F outside that range
• Battery: 9V, approx. 20–35 hours typical life
• Auto power-off: 15 minutes
