The Testo 0635 9532 is a 16mm vane probe and is used to measure air velocity, volume flow and humidity. Please note, this probe cannot be used on its own - it must be used with a compatible Testo multifunction instrument.

Vane probe - features

Use the fixed cable to connect the vane probe to the measuring instrument. The probe is equipped with a telescope, which can be extended to a maximum length of 0.85 m. The immersion depth is easy to read off thanks to the scaling on the telescope.

The clearly structured measurement menu for volume flow makes the measuring instrument intuitive to operate. The volume flow is precisely calculated thanks to convenient input of the size and geometry of the duct cross-section. Timed and multi-point mean calculation, average volume flow, current reading and min./max. values are displayed in the measuring instrument.

Intelligent calibration concept

You will get exceptionally accurate measurement results with the digital probe, because the measuring instrument makes measurement uncertainty a thing of the past. You only need to send the probe in for calibration - so the measuring instrument remains in continuous use.
 
Areas of application for the vane probe

Ventilation ducts: Use the vane probe to measure air velocity in ventilation ducts with reliability. Benefit from fast calculation of the volume flow: in the “volume flow” measurement menu of the compatible measuring instrument (please order separately), configure the dimensions and geometry of the duct cross-section - the measuring instrument shows you the volume flow straight away.
