    The testo 400 Air Flow Kit with 16 mm Vane Probe is an advanced, all-in-one solution for professionals performing detailed airflow and indoor air quality (IAQ) assessments. This powerful kit includes the testo 400 universal IAQ instrument, designed to measure all key climate-related parameters—such as flow velocity, temperature, humidity, differential pressure, CO₂, and CO.

    Ideal for performing grid-based volume flow measurements in air ducts according to EN ISO 12599 and ASHRAE 111, the kit includes a 16 mm vane probe for duct work, a 100 mm vane probe for ceiling and outlet measurements, and a high-precision humidity/temperature probe. All probes are easily attachable to the included Bluetooth® handle, enabling convenient wireless operation.

    With the extendable telescope and 90° angle adapter, the testo 400 allows for ergonomic and ladder-free measurements even at ceiling outlets. Backed by smart, menu-guided workflows and integrated data management software, this kit is a trusted tool for balancing, commissioning, and verifying HVAC system performance—while minimising measurement uncertainty through the use of digital probes.
