Overview

The Testo 440 dP Air Flow ComboKit 1 provides a comprehensive solution for HVAC professionals, enabling precise air flow measurements without the hassle of cables. This kit is specifically designed for all relevant measurements in ventilation ducts and at air/ceiling outlets.

It includes the Testo 440 dP air velocity and IAQ measuring instrument with a differential pressure sensor. Complementing this are a 100 mm vane probe head and a 9 mm hot wire probe head, both attachable to the universal Bluetooth handle. For extended reach and flexibility, these probe heads can be combined with the included 1.0 m extendable telescope.

Why It Matters

Accurate air flow and indoor air quality (IAQ) measurements are fundamental for ensuring optimal HVAC system performance, energy efficiency, and occupant comfort. This kit empowers tradies to quickly identify issues, verify system parameters, and comply with ventilation standards, leading to healthier indoor environments and reduced operational costs.
