Use this large-size anemometer to easily determine air flow within large ducts and other HVAC applications.
Equipped with a built-in, 100mm diameter measurement vane, the Testo 417 measures air flow velocity, volume flow and temperature over a wide measurement area. It'll also determine the direction air flow is travelling and display this on the screen. When measuring volume flow, it's possible to directly enter the duct area size into the Testo 417, ensuring you always get accurate results.
This anemometer also comes with a timed and mean point value function - using this mode, it's possible to determine information on average volume flow, flow velocity and temperature over a period of time. Alternatively you can use the MAX/MIN function to display the maximum or minimum value taken over a period of time, or use the built-in data hold function to freeze the current value on the screen.
Please note calibration certificate included is from day of manufacture, not the day of purchase. We can calibrate your meter from your day of purchase to ensure you get an entire year's worth of operation before calibration is due again. Use the dropbox at the top of the page to add calibration for this product
The Testo 417 is also compatible with a selection of large-size funnels which further expand its measurement area. You can buy these separately, or alternatively you can purchase a kit version of the 417 which includes these funnels as standard.
