The Testo 0635 9435 is a 4 inch vane probe for Testo 435 HVAC. It has measuring ranges of 0 to 50 °C (32 to 122 °F) and 59.1 to 3937 (0.3 to 20 m/s) with accuracies of ±0.5 °C to 0.9 °F and ±19.7 fpm (0.1 m/s) + 1.5% of mv.
The 0635 9435 is able to determine the flow of velocity or volume flow at ventilation outlets using its 4 in (100 mm) diameter vane probe. The vane probe can achieve extremely high precision if used with the testovent 417 volume flow straightener (optional).
