testo 405 is a thermal anemometer. It allows the precise
measurement of air flow velocity, volume flow and
temperature. With the extendable telescope (up to 300 mm),
testo 405 is particularly suited for measuring the flow
velocity in ducts. Thanks to the attachment included in
delivery, the telescope can be optimally positioned in a
duct.
m/s
°C
The testo 405 measures especially accurately in the range
from 0 and 2 m/s. Low air flow velocities such as at
draughty windows, for example, can thus be localized
exactly and measured extremely accurately.
The display can be rotated into different positions. This
enables optimum readout of the measurement values.
