ISO Calibration Certificates: Available for velocity and hot wire, vane anemometer, Pitot tube with various calibration points

Additional Features: The testo 405 is particularly accurate in measuring low air flow velocities, such as those found at draughty windows. The instrument's display can be rotated for optimal viewing of measurement values.

Catalog excerpts

Flow velocity measuring instrument with temperature Volume flow measurement up to 99,990 m3/h Display illumination 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 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.
