The Testo 440 dP Air Flow ComboKit 2 with Bluetooth is a professional air velocity and IAQ measuring kit designed for HVAC technicians working on ventilation ducts, air outlets, ceiling diffusers and indoor comfort checks. Built around the testo 440 dP measuring instrument, this kit adds an integrated differential pressure sensor plus wireless and wired probes for accurate airflow, humidity, temperature and pressure measurement.
Designed for commissioning, balancing and servicing air conditioning and ventilation systems, the kit includes both Ø100 mm and Ø16 mm vane probe heads, a humidity/temperature probe head, Bluetooth handle, telescopes and a robust carry case. The testo 440 dP automatically recognises connected probes and provides structured measurement menus to simplify volume flow, duct velocity, outlet measurement and differential pressure testing.
