Measuring air flow velocities and correctly calculating the volume flow at ventilation outlets can present a challenge. Use the testovent 417 funnel set (in conjunction with the appropriate measuring equipment) to measure the volume flow at ventilation grilles and plate outlets conveniently and accurately. Using the funnels will save you time, since there is no need to use the time-consuming loop method for calculating the mean.
Convenient, quick volume flow measurement.
With the funnel set, the time-consuming loop method is a thing of the past.
Suitable for outlets up to 300 x 300 mm.
Easy to assemble.
The funnel kit comprises a funnel for measuring at plate outlets (200 x 200 mm) and a funnel for measuring at fans (330 x 330 mm) in combination with:
testo 445 and testo 400 with 100 mm vane probe 0635 9340.
testo 435 from firmware 2.06 (instruments manufactured from 2007 onwards) or 1.14 (instruments manufactured up to 2006) with 100 mm vane probe 0635 9435.
