Fieldpiece STA2 Thermo-Anemometer

STA2 — thermo-anemometer for measuring air velocity and temperature in ductwork, with automatic volumetric flow (CFM) calculation.

Applications

• air velocity and temperature measurement in ventilation and air conditioning ducts
• duct air balancing
• volumetric flow (CFM) calculation from velocity and cross-sectional area
• duct traversing using the telescoping probe

Key Features

• 38" telescoping probe with laser-engraved scale and flat edge for accurate duct positioning
• Dual display showing CFM, air velocity, or temperature simultaneously
• Automatic CFM calculation from air velocity and duct area
• Hands-free operation using the cone stand and magnetic hanger
• Turbulence averaging — time and multi-point averaging minimises the effect of turbulence
• Auto-off after 15 minutes of inactivity (APO)
