Use the 100 mm Testo 0635 9343 Digital Vane Probe to determine flow velocity and volume flow at ventilation outlets. Integrated temperature measurement enables the vane anemometer to measure temperatures up to140 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 480 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.

The 0635 9343 Digital Vane Probe offers maximum digital measurement reliability. The digital probe allows readings to be processed directly in the probe. This technology eliminates instrument measurement uncertainty. Calculating the determined calibration data in the probe generates a zero-error display.
