Testo 425 Digital Hot Wire Anemometer with Smart App Connection
Switch on, measure and know more immediately
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. The connection to the testo Smart App enables configuration, display (also as second screen) and storage as well as documentation of the measurement directly in the App.
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 inches, 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. 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.
