0563 0417 417 - Digital 4 in Vane Anemometer with App connection by Testo

The compact testo 417 4 inch vane anemometer was developed to ensure precise results when measuring air inlets and outlets of air conditioning and ventilation systems. Time and point average values as well as the volume flow are automatically calculated in the instrument and shown on the display.

This allows balanced commercial and residential ventilation systems to be adjusted especially efficiently – including quick documentation with the testo Smart App. In addition, the App not only supports you in configuring the measuring instrument and takes over display, storage and documentation of the measured values – it also turns your smartphone into a second display.

testo 417 is also available in two practical kits: The testo 417 kit 1 includes two measuring funnels for plate outlets and ventilation grilles. These can be easily attached to the vane, covering a wide range of outlet sizes and formats.

In addition to the two measuring funnels, the testo 417 kit 2 includes a volume flow straightener to achieve precise results even at swirl diffusers.

• 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
• Durability through compact design with robust housing

0563 0425 425 - Digital Hot Wire Anemometer with App connection by Testo

Optimally adjusted air conditioning and ventilation systems are a decisive factor for modern buildings. Accordingly, it is important to use the appropriate measurement technology to ensure that the flow, temperature and volume flow in the ventilation duct are correct.

The testo 425 thermal anemometer is your fast, easy and precise companion. The cable-connected telescopic probe can be extended up to 32 in., making it easier to work overhead or in large diameter ducts. All relevant calculations, such as volume flow or time and point averages, are performed automatically by the and compact measuring instrument.

Configuration of the measuring instrument, display and storage of measured values as well as documentation are available with the testo Smart App. This also turns your smartphone into a second display to give you more flexibility on the job.

• Simple, fast and precise flow and temperature measurement plus volume flow calculation in the ventilation duct
• More flexibility for duct measurements with the cableconnected telescopic probe (maximum length 32 in.)
• Fast in-app (duct) configuration, graph history, second screen and measurement data memory in the testo Smart App
• Timed and point mean value calculation
• Durability through compact design with robust housing
