nnnn

testo 405 is a thermal anemometer. It allows the precise

nnnn

measurement of air flow velocity, volume flow and

nnnn

temperature. With the extendable telescope (up to 300 mm),

nnnn

testo 405 is particularly suited for measuring the flow

nnnn

velocity in ducts. Thanks to the attachment included in

nnnn

delivery, the telescope can be optimally positioned in a

nnnn

duct.

nnnn

The testo 405 measures especially accurately in the range

nnnn

from 0 and 2 m/s. Low air flow velocities such as at

nnnn

draughty windows, for example, can thus be localized

nnnn

exactly and measured extremely accurately.

nnnn

The display can be rotated into different positions. This

nnnn

enables optimum readout of the measurement values.
