Kit testo 440 – wind speed meter (Bluetooth) (Rotor probe Ø 100 mm)

Kit testo 440 air velocity meter with 100 mm diameter impeller probe (Bluetooth), including integrated temperature sensor stored neatly in a suitcase.

The testo 440 wind velocity meter product set includes:

Intuitive: clearly structured measurement menus for volumetric flow rate, turbulence level, cooling/heating output, mold detection and long-term measurements, such as CO₂

Wireless: Bluetooth® probe for more convenient measurements and less cable clutter

Intuitive: clearly structured measurement menu for volume flow; Parallel determination of air velocity, volume flow and air temperature

Accurate: get consistent results quickly, even in turbulent air flows – using the funnel and flow straightener (optional to order)
