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.
