testo 405
testo 405 is a thermal
anemometer. It allows the
measurement of air flow velocity,
volume flow and temperature.
testo 405 is ideal for measuring
the flow in ducts or at duct
openings or draughty windows.
• Volume flow calculation up to
99,990 m3/h
• Ideal for measurements in ducts
• Telescopic handle to 300 mm

Attachable protective cap
Flow measurement at a duct outlet with 40 mm vane
testo 410-1 measures air speed
and temperature. It is ideal for
spot measurements at air outlets
on account of its 40 mm vane.
Timed mean calclation is
possible.
In addition to air speed and
temperature, testo 410-2 also
measures air moisture. Testo's
own, patented humidity sensor
guarantees measurements you
can build on. In this way, air
conditions can be reliably
checked.

values
• Windchill calculation for outside
areas (perceived temperature)
• Display illumination
Additional benefits of testo 410-
2:
• Air humidity measurement with
long-term stable Testo humidity
sensor
• Incl. dewpoint calculation and
wet bulb
