-
Intuitive: clearly structured measurement menu for volume flow and determination of air velocity, humidity and temperature in ventilation ducts or at ventilation outlets
-
Clever: vane probe (Ø 16 mm) with telescope (0.85 m) – combine the vane probe (Ø 100 mm) with Bluetooth with the telescope for ceiling outlets or the funnel set for plate outlets (please order separately) as required
-
Convenient: wireless probe, internal data storage and USB port for data export
-
As multifaceted as your challenges themselves: the testo 440 can be expanded with a large portfolio of digital probes
