Testo 440 ComboKit air flow measurement kit is designed to measure the parameters of ventilation ducts and air outlets. The kit includes a Testo 440 air velocity and indoor air quality measuring instrument, a paddle probe (Ø 100 mm) and a hot wire probe with temperature sensor.
Testo 440 ComboKit for air flow measurement is:
- Intuitive: Clearly structured menus and parallel setting of air velocity, humidity and temperature in ventilation ducts or at ventilation outlets
- Digital: All accessories (hot wire probe with telescope (0.85 m), paddle probe (Ø 100 mm)) can be connected via Bluetooth
- Convenient: Wireless probe, internal data storage and USB interface for data export
- Multifunctional: air velocity and air quality measurement can be used with a wide range of digital probes
