Testo 400 Air Flow Kit with Hot Wire Probe

Overview

The Testo 400 Air Flow Kit with hot wire probe is designed for indoor air quality (IAQ) professionals who need accurate low-velocity and duct airflow measurement. At its centre is the testo 400 universal IAQ measuring instrument with intuitive measurement menus, supplied with a hot wire probe head (including temperature and humidity sensor), a Ø 100 mm vane probe head and a high-precision humidity/temperature probe head, all of which attach to the supplied Bluetooth® handle.

The hot wire probe excels at low air velocities, making the kit ideal for ventilation and duct measurements, while the vane probe handles higher velocities and air outlets. For measurements at ceiling outlets, simply combine the 100 mm vane probe with the telescope, which extends up to 1.0 m, and the 90° angle adapter. Everything is supplied in a dedicated transport case for airflow measurements.
