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.

0554 4173 Testovent 417 Flow Straigthener Set by Testo

The air flow at swirl outlets is subject to major turbulence. As a result, it is very difficult to measure the volume flow correctly at these outlets using only a vane anemometer and funnels for the measurement. Higher or lower measurement results are generated depending on the flow direction in which the swirl hits the vane. This means that the ventilation system cannot be optimally adjusted.

Testo is the only manufacturer to offer a solution which enables you to take simple, precise measurements at swirl outlets. In conjunction with a funnel, the patented volume flow straightener testovent 417 offers you ideal assistance in measuring the volume flow at swirl outlets. The volume flow straightener makes it possible to change the turbulent flow to an almost uniform flow, which can then be reliably recorded using an optional vane anemometer.

In this set you get the testovent 417 volume flow straightener plus two funnels for ventilation grilles and plate outlets (testovent 417 funnel set). The funnels and the flow straightener can be conveniently transported in the practical case.

To measure the volume flow, you will also need a compatible vane anemometer, which you can order separately for example, the testo 417 vane anemometer or the vane probes (Ø 100 mm) for the testo 435 and testo 480.

• Convenient, quick volume flow measurement
• Accurate measurement even in turbulent flows
• Patented volume flow straightener

VPE Professional Kit by Superior AccuTrak

The Patented Superior AccuTrak® VPE represents state-of-the-art technology for pinpointing leaks is air conditioning and refrigeration systems. AccuTrak® is extremely sensitive to the ultrasonic sound of a turbulent gas leak. Using a technology called "heterodyning" it translates the sound to a lower frequency which your ear can interpret. AccuTrak maintains the original sound characteristics making it possible to distinguish leaks from other competing background sounds. AccuTrak is so sensitive you can actually hear the blink of an eye, yet most background noise will not interfere with detection accuracy.

The AccuTrak® VPE Professional Kit is designed for technicians who work in noisy places, or who regularly need to find smaller leaks. The VPE Professional Kit includes all the great features of our VPE Standard Kit upgraded with professional Noise Cancelling Headphones and a larger case to keep everything together. These high quality headphones eliminate all background noise, allowing a technician to effectively find the smallest leaks even in very loud environments. You can choose the standard style professional headphones, or the hardhat compatible version same price!
