The testo 425 digital hot wire anemometer with App connection is fast, easy and precise companion. All relevant calculations, such as volume flow or time and point averages, are performed automatically by the particularly robust and compact measuring instrument.
- Simple, fast and precise flow and temperature measurement plus volume flow calculation in the ventilation duct
- More flexibility for duct measurements with the cable connected telescopic probe (maximum length 820 mm) making it easier to work overhead or in large diameter ducts
- Timed and point mean value calculation
- Durability through compact design with robust housing
- Housing material of ABS and PC/TPE
Fast in-app (duct) configuration, graph history, second screen and measurement data memory in the testo Smart App. Configuration of the measuring instrument, display and storage of measured values as well as documentation are all particularly convenient with this App. This also turns your smartphone into a second display. Gives clear graphical presentation of readings, like as a table, for quick interpretation of results. Creates digital measurement reports including photos as PDF/CSV files on site and send via e-mail.
