Intuitive: clearly structured measurement menu for volume flow and parallel determination of air velocity, differential pressure, humidity and temperature in ventilation ducts, at ventilation outlets and in work rooms;
Space-saving: combine the universal Bluetooth handle with the humidity/temperature probe head or extendable telescope (1.0 m). Vane probe heads (Ø 16 mm, Ø 100 mm) can simply be plugged onto the telescope;
Convenient: wireless probes, internal data storage and USB port for data export;
As multifaceted as your challenges themselves: the testo 440 dP has an integrated differential pressure sensor and can be expanded with a large portfolio of digital probes
