- Intuitive: clearly structured measurement menu for volume flow and parallel determination of air velocity, humidity and temperature in ventilation ducts or at air outlets
- Precise: combine the vane probe 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 your data export
- As multifaceted as your challenges themselves: the air velocity and IAQ measuring instrument can be expanded with a large portfolio of digital probes
Kit for carrying out measurements at air outlets: the testo 440 air velocity and IAQ measuring instrument and the vane probe (Ø 100 mm) with Bluetooth including temperature sensor are all safely stowed away in the case. So you can get down to work straight away!
