testo 440dP – air flow meter 2 (Bluetooth)

Producer: TESTO

SKU: TESTO-0563-4410 Category: Gas concentration measuring device

Intuitive: clearly structured measurement menu for volumetric flow rate and parallel determination of air velocity, pressure differential, temperature, humidity in ventilation ducts, at air outlets or in working rooms
Save space: with the combination of the universal Bluetooth handle and the temperature/humidity probe or the telephoto tube can be extended to 1.0 m in length. Additionally, the vane probe (Ø 16 mm or Ø 100 mm) can be easily connected to the telephoto tube
Convenient: with internal memory, wireless probe and USB data retrieval port
You can extend the functionality of the testo 440dp: with the range of compatible probes offered by Testo (optional to order)

Perform a wide range of measurement tasks: use the testo 440dp air flow measuring kit to handle all relevant measurements in ventilation ducts and air outlets (on the floor or ceiling). This measuring equipment set includes: an integrated testo 440dp multifunction meter differential pressure sensor and two impeller probes (Ø 100 mm and Ø 16 mm); a temperature/humidity probe. All three of these probes can be connected handle Bluetooth^® versatile. Both vane probes can be combined with the teletube included in the kit for more convenient ceiling wind measurements.
