Testo 440 delta P Air Flow ComboKit 1 with Bluetooth®

  • Intuitive: clearly structured measurement menu for volume flow and parallel determination of air velocity, differential pressure, humidity and temperature in ventilation ducts or at ventilation outlets
  • Space-saving: simply combine the universal Bluetooth handle with the 100 mm vane or hot wire probe head and the extendable telescope (1.0 m)
  • 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

Product Description

Carry out measurements without any annoying cables: use the kit to handle all relevant measurements in ventilation ducts and at air/ceiling outlets.
You will receive the testo 440 dP air velocity and IAQ measuring instrument including differential pressure sensor and the 100 mm vane probe head and hot wire probe head (Ø 9 mm) for attachment to the universal Bluetooth® handle supplied.
To make measurements more convenient, both probe heads can be combined with the telescope included in the kit. The equipment can be transported safely and conveniently in the robust case.
