The Testo 0635 1032 Digital Hot Wire Probe is used to determine air velocity, volume flow and air temperature. The fixed cable on the handle is used to connect the hot wire probe to a measuring instrument (sold separately). The probe is equipped with a telescope, which can be extended to a maximum length of 33.5 inches (0.85 m). To ensure accurate measurement results, air density compensation is carried out via the integrated absolute pressure measurement. When you are not using the hot wire probe, the rotatable protective cap protects the air velocity sensor from dirt and mechanical stress.

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

Users receive exceptionally accurate measurement results with the digital probe, because the measuring instrument makes measurement uncertainty a thing of the past. Only the probe needs to be sent in for calibration - allowing the measuring instrument to remain in continuous use.

Areas of Application for the Hot Wire Probe

Ventilation ducts: Use the hot wire probe to reliably measure air velocity and air temperature in ventilation ducts. Benefit from fast calculation of the volume flow: in the "volume flow" measurement menu of the compatible measuring instrument (sold separately), configure the dimensions and geometry of the duct cross-section - the measuring instrument shows you the volume flow straight away.

Plate outlets and ventilation grilles: For convenient, accurate measurements at plate outlets and ventilation grilles, use the hot wire probe in conjunction with the testovent 410 or testovent 415 funnel set (sold separately). This makes it easy to test the exhaust air - such as in the controlled ventilation of living spaces.
