Testo 440 16mm Telescopic Vane Kit

The Testo 440 16mm Telescopic Vane Kit is a practical solution for measuring air velocity, volume flow and wider IAQ parameters in ventilation ducts. Supplied with the Testo 440 Air Velocity and IAQ measuring instrument and a wired 16mm vane probe, it is well suited to HVAC professionals who need accurate, repeatable airflow measurements in day-to-day commissioning, servicing and troubleshooting work.

A key strength of the kit is its suitability for duct measurements in harder-to-reach areas. The vane probe features an integrated telescope extendable to 0.85m, helping users position the sensor more effectively in ducts and at height. Combined with the Testo 440’s structured measurement menus for duct air velocity and volume flowm this helps make on-site measurements faster, more consistent and easier to carry out.

The Testo 440 platform also adds useful long-term flexibility. It can be used with a range of additional Bluetooth and wired probes for other IAQ measurements, while the instrument can store up to 7,500 readings and export results via USB as CSV files for reporting and analysis. Supplied in a basic case, the kit offers a convenient and expandable setup for professional airflow measurement.
