Force and mechanical measuring equipment
Compact wind velocity meter testo 425 with telephoto probe, thermal fiber sensor. The ideal device for the simple, fast, accurate determination of wind velocity and volumetric flow rate in the ventilation ducts of air conditioning/ventilation systems. Connect easily with testo Smart App (completely Free download).
Optimally adjusted ventilation and air conditioning systems are decisive for buildings. Therefore, it is important to use the right measurement technology to ensure that the velocity, temperature and volume flow in the ventilation duct are always configured correctly.
The testo 425 anemometer is your companion for quick, easy and accurate measurements. The teleprobe with cable connection can be extended up to 820 mm, making it easy to measure objects overhead or in large diameter ventilation ducts.
All relevant calculations, such as volumetric flow rates or time/point averages, are performed fully automatically by the testo 425. In addition, wireless connection to the app is possible. testo Smart App also helps you: configure the measuring device, display and store measured values, as well as all documents related to the measurement.
