Optimally adjusted air conditioning and ventilation systems are a decisive factor for modern buildings. It is therefore important to use the right measurement technology to ensure that the flow, temperature and volume flow in the ventilation duct are correct. This is where the testo 425 thermal anemometer can help you quickly, easily and precisely. The cable-connected telescopic probe can be extended to 820 mm, making it easier to work overhead or in large-diameter ducts. All relevant calculations, such as volume flow or temporal and punctual mean values, are performed automatically by the particularly robust and compact measuring device. By the way: you can configure the measuring instrument, display and save the measured values and document them particularly conveniently with the testo Smart App. This also turns your smartphone into a second display
