Datasheet Testo 417 (EN) | Instruction Manual Testo 417 (EN)
The comprehensive 100 mm vane anemometer Testo 417 kit 2 includes two measurement funnels and a specialized volume flow straightener. This system is engineered for precise determination of flow velocity, volume flow, and temperature at plate and swirl outlets of air conditioning and ventilation systems. The straightener eliminates turbulent air profiles at swirl diffusers, while integration with the testo Smart App ensures quick configuration, remote display, and reliable measurement data memory tracking.
B2B Industrial Applications
- Swirl Outlet Verification: Calibrating turbulent and rotational air vectors at commercial swirl diffusers using the volume flow straightener.
- Residential Ventilation Balancing: Comprehensive regulation of supply and exhaust flows at plate outlets with dedicated test funnels.
- HVAC System Commissioning: Direct multi-point calculation and recording of volumetric discharge for comprehensive industrial system compliance.
