The Testo 417 anemometer features a fixed 100 mm vane to measure airflow, volume flow and temperature. Flow direction is also indicated in the display which makes this instrument an extremely versatile product especially when used in conjunction with the volume flow hood set.
Hood sizes 200 mm diameter and 330 mm x 300 mm rectangular.
All hire kits come complete with an ISO traceable air volume calibration.
- Direction of flow recognition
- Temperature, flow and volume flow measurement
- Multi-point and timed mean calculation
- Max/min values
- Hold button to freeze readings
- Display light
- Auto Off function
For details of the Testo volume flow hood sets available for purchase please see separate entry within the air capture hood section of the web site. This is ideal for testing ventilation systems to Part F of the UK Building Regulations. UKAS calibrations for air volume are also available from the BSRIA Instrument Solutions Laboratory at an additional cost.
