Application
The comfort probe 0628 0143 is used in conjunction with testo 480
to determine the air velocity and draught risk in accordance with
DIN EN 13779.
Observe the information on the measuring process in the
instrument instruction manual.

The digital probe allows measurement values to be
processed directly in the probe. This technology eliminates
instrument measurement uncertainty.
For calibration, the probe alone (without the hand
instrument) can be sent away.
Calculating the determined calibration data in the probe
generates a zero-error display.
