The compact hot wire anemometer testo 425 with telescopic probe is ideal for simple, fast and precise determination of flow velocity and volume flow in ventilation ducts of air conditioning and ventilation systems. 

  • - 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).
  • - Fast in-app (duct) configuration, graph history, second screen and measurement data memory in the testo Smart App.
Regular price $1,017.00 AUD + GST

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 820 mm, 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 particularly robust and compact measuring instrument.
Incidentally: Configuration of the measuring instrument, display and storage of measured values as well as documentation are all particularly convenient with the testo Smart App. This also turns your smartphone into a second display.
