VAC measuring instruments from Testo
provide the highest level of precision from 0.01 m/s to 9999 m3/h. For any air
conditioning and ventilation professional, measuring flow velocity accurately
is not easy. Whether for the precise determination of volume flow, quick spot
measurements in ducts or recording turbulent flows at outlets – without
suitable measuring instruments, it is impossible to ensure optimum indoor air
in residential and non-residential buildings
For this reason, Testo offers the optimum
solution for every measurement task and measurement range: whether thermal
probes, vane anemometers, differential pressure measuring instruments or
multifunction instruments. Our patented flow straighteners provide added
precision, even in turbulence at outlets. Find information now on how to measure
flow velocity more efficiently.
Accurate measurement in ducts
You obtain the most accurate results when
you measure directly in the duct. To compensate non-homogenous flows, a grid
measurement is recommended. For this purpose, you determine the flow velocity
values at several points in the duct cross-section, enter the cross-section
dimensions – and your ventilationmeasuring instrument from Testo calculates the mean value and the volume
flow for you automatically and reliably.
Precise measurement at outlets
If the ventilation duct is inaccessible,
the measurement takes place directly at the outlet. In adjustment work too, the
air input and output is tested where the air flows into the room. However,
turbulent flows at swirl and plate outlets can severely falsify your
measurement results. For this reason, we recommend the use of funnel measuring
instruments with a flow straightener (testo 420, testo 417 set 2).
Multifunctional measurement in ducts and
at outlets
Multifunction measuring instruments give
you as a VAC professional maximum flexibility. The multifunction VAC measuring
instruments testo 435-4 and testo 480 can be extended with various probes. In
addition to flow velocity, volume flow, temperature and humidity, you measure
absolute and differential pressure, light intensity, radiated heat, degree of
turbulence and CO2 concentration – with only one instrument.
