Use the Testo 0635 9435 Vane Probe to determine flow velocity or volume flow at ventilation outlets. Integrated temperature measurement enables the vane anemometer to measure temperatures up to 122 degrees F.

For convenient, accurate measurements at plate outlets and ventilation grilles, we recommend that you use the vane/temperature probe in conjunction with the Testo 435 measuring instrument and the Testovent 417 funnel set (both optional, available separately). This guarantees simple testing of incoming/outgoing air, such as in the controlled ventilation of living spaces.

If you add in the Testovent 417 volume flow straightener (optional, available separately), you can achieve an impressively high level of precision when carrying out measurements at swirl outlets.
