Extech AN300-C Anemometer / Air Flow

The Extech AN300-C large vane anemometer validation set features a ø100 mm low-friction rotating wheel engineered explicitly for air cone diagnostics across HVAC return diffusers and grilles. Driven by standard internal battery voltage, it converts raw physical velocities up to 5900 ft/min directly into real-time volumetric calculations. This compact diagnostic wand records velocity patterns smoothly, displaying values instantly onto a digital panel face.
