The Testo compact, large-area anemometer with a built-in flow velocity and temperature vane. It measures flow velocity, volume flow and temperature. Due to the integrated measurement with the 100 mm vane, it is ideally suited for measurements at air input and output vents. The flow direction, that is blowing or sucking flow, is visible in the display. The optimum funnel set additionally allows measurements on ventilation grilles and disc outlets.
