0554 4172 Testovent 417 Flow Straightener by Testo

Testo is the only manufacturer providing a solution the problem of measuring equally easily and accurately at swirl outlets. The innovative volume flow straightener testovent 417 supports you perfectly in flow velocity measurement at swirl outlets. The volume flow straightener allows redirection of the swirling flow to an almost uniform flow which can then be reliably recorded with a vane anemometer or vane probes. Measurements at swirl outlets without the volume flow straightener lead to lower or higher measurement results, depending on the flow direction in which the swirl impacts onto the vane.

The volume flow straightener is used in combination with the optional measurement funnel testovent 417 and the optional vane anemometer testo 417 or the vane probes (Ø 100mm) of testo 435, testo 440 and testo 480.

• More accurate volume flow measurement independent of the swirl direction
• Reliable measurement results on swirl outlets
• Flow straightener retrofittable for existing Testo funnels sets

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
• Included in the set: volume flow straightener, two funnels and a practical case

8721 0025 Flow Matrix by Testo

The air flow grid (in conjunction with the appropriate measuring instrument) is your ideal measurement solution for determining flow velocity and volume flow on laminar flow supply air diffusers.

Use the air flow grid to carry out accurate measurements on laminar flow supply air outlets. Use in conjunction with a differential pressure measuring instrument (e.g. testo 420, testo 480 or testo 435-4) to calculate flow velocity and volume flow.

The air flow grid (360 x 360 mm) can be used over a large area and is particularly suitable for carrying out measurements on HEPA filters and safety cabinets in cleanrooms.

Particularly useful: you can also use the screw-on telescope (can be extended to 1800 mm) to carry out volume flow measurements on high ceiling diffusers.

• Volume flow measurement on large supply air diffusers, HEPA filters and safety cabinets in cleanrooms
• The telescope makes it possible to carry out measurements on high ceiling diffusers
• Ideal for large surface areas
• Air flow grid dimensions: 360 x 360 mm
