testo 417 - Digital 100 mm vane anemometer with App connection, battery & calibration protocol 

The compact 100 mm vane anemometer testo 417 is the ideal solution for simple, fast and precise determination of flow velocity and volume flow at air intake and outlet vents of air conditioning and ventilation systems. Adjustment for balanced residential ventilation or measurement at swirl outlets is also child's play with the testo 417 kits including funnel and flow straightener. Thanks to the connection to the testo Smart App, configuration, display (also as second screen) and storage as well as documentation of the measured values are dealt with quickly and without any complications.

• Easy, fast and precise measurement of flow, volume flow and temperature at air inlets and outlets
• Efficient regulation of balanced residential ventilation and fast documentation with the testo Smart App
• Fast in-app configuration, graph history, second screen and measurement data memory in the testo Smart App
• Timed and point mean value calculation

Additional Information:

• Item Code: Testo-417

The NEW testo 420 air capture hood for larger air inlets and outlets enables fast and precise calculation of the overall air capture on HVAC systems. It helps in frequent air capture calculations in large rooms and measurements above head height can also be carried out reliably and comfortably, thanks to its ergonomic handles and tiltable display which results in a significant loss in the overall weight of the instrument.

Features:

• Significantly light with a weight of 2.9 kg
• Precise measurement even at swirl outlets
• App integration via Bluetooth for fast and easy monitoring and reporting on site
• Removable and tiltable measuring instrument with a large display

Additional Information:

• Item Code: Testo-420

Product Details:
