The 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 820 mm, making it easier to work overhead or in large diameter ducts.
Precise flow, temperature plus volume flow calculation
Timed and point mean value calculation
Operating temprature is -20 to +70 °C
Battery life is 35 hours
