Vane probe with Bluetooth including temperature sensor – features

The readings of the vane probe are transmitted to your measuring instrument via Bluetooth, up to a distance of 20 m.

The clearly structured measurement menu for volume flow enables the measuring instrument to be operated intuitively. The volume flow is precisely calculated thanks to convenient input of the size and geometry of the duct cross-section. Timed and multi-point mean calculation, average volume flow, current reading and min./max. values are displayed in the measuring instrument.

Particularly useful: press the button on the vane probe to operate the measuring instrument. For example, to store individual readings for multi-point mean calculation or to start and stop measurement series for mean calculation over time.

 

Wireless and space-saving: more applications, less equipment

Endlessly versatile: a universal handle can be connected to all probe heads – so you can master more applications using less equipment and save space. The Bluetooth handle makes it more convenient to carry out your measurement and guarantees less cable clutter in the case.

Or order the cable handle to connect testo probe heads. This is an advantage if Bluetooth signals are not permitted. If the vane needs to be replaced in the distant future, you can change the probe head.

If required, you can also fit the vane probe with the extendable telescope with 90° angle and, if necessary, the telescope extension (both can be ordered separately; in combination 2 m long). This makes it easy to measure at ceiling outlets.

 

Intelligent calibration concept

You will get exceptionally accurate measurement results with the digital vane probe, because the measuring instrument makes measurement uncertainty a thing of the past. You only need to send the probe head in for calibration – so the measuring instrument remains in continuous use.

 

 
Areas of application for the vane probe with Bluetooth

Air/ceiling outlets: Use the vane probe to determine air velocity and volume flow at air outlets. During loop-pattern scanning of the grille’s cross section, the air velocity values are integrated and averaged across a large area of 100 mm. As a result, precise measurement results are achieved with the loop measurement.

For measurements at ceiling outlets: the extendable telescope (1.0 m long) with easy-to-read scaling and 90° angle is easy to attach to the vane probe. The 90° angle ensures that the probe is positioned correctly under the ceiling. For high ceilings, you can also use the telescope extension, attaining a total length of 2 metres (please order the extendable telescope and telescope extension separately).

Plate outlets, ventilation grilles and swirl outlets: For convenient, accurate measurements at plate outlets and ventilation grilles, we recommend using the vane probe with the testovent 417 funnel set (please order separately). This guarantees simple testing of incoming/outgoing air – such as in the controlled ventilation of living spaces.

If you add in the volume flow straightener (please order separately), an impressively high level of precision can be achieved when carrying out measurements at swirl outlets.
