The testo440 probe system:
you’ll never want to work any
other way again.
All testo440 air velocity probes for measurements in ducts have a
scaled, extendable telescope (optionally extendible from 1 to 2 m).
The 100mm vane probe can be easily combined with the 90° angle
and telescope, making measurements at ceiling outlets easier.

Intelligent calibration concept: only the probes need to be
calibrated. Handles and measuring instrument still work and can
continue to be used for measurements with a different probe.
