Testo Air Flow ComboKit With Bluetooth, 440, Delta P, -20 to 50 Deg.C

The testo 440 dP multifunction measuring instrument, the vane probe and the hot wire probe head all feature ease of use, maximum convenience for the adjustment of air-conditioning and ventilation systems and an intelligent calibration concept.

• With an integrated differential pressure sensor, e.g. for checking filters, for Pitot tube measurement (Pitot tubes can be ordered separately) or K factor measurement
• Automatic detection of probes, e.g. vane probe, hot wire probe
• Large, backlit colour display
• Other practical measurement menus, e.g. determination of volume flow via differential pressure and K factor, long-term measurement, volume flow measurement with a funnel, etc.
• Connectable probes: 1 x digital probe with cable or 1 x Temperature NTC TUC, 1 x digital Bluetooth probe or testo Smart Probe, 1 x differential pressure (internal), 1 x Temperature TC Type K
