The compact vane anemometer testo 417 in set 2 including two measuring transducers and a rectifier has been developed to make measurements of air inlets and outlets as well as disk valves and air conditioning and ventilation systems much easier. The integrated 100 mm impeller ensures precise results quickly. Timed and point mean values as well as the volume flow are calculated automatically in the device and shown on the display. This allows controlled home ventilation to be controlled efficiently - including rapid documentation with the testo Smart APP. The APP also supports you not only with the configuration of the measuring device and displays, stores and records the measurement values â it also makes your Smartphone a second display. The testo 417 set 2 includes two measuring funnels and a volumetric flow rectifier for precise results even at twist outlets.This text is machine translated.
