Testo 425 Compact Digital Hot Wire Anemometer

The Testo 425 model, a cutting-edge hot wire anemometer, comes equipped with a telescopic probe and smart App integration. It actively facilitates rapid, accurate, and effortless measurements of airflow and volume flow in ventilation ducts.

In the realm of modern architecture, ensuring robust ventilation is imperative. The Testo 425 anemometer excels in this aspect by simplifying the verification of air conditioning and ventilation system efficiency. Its probe, which can extend up to 820 mm, makes it particularly suitable for working in challenging overhead situations or within larger ducts. This durable, compact instrument autonomously performs critical calculations, including volume flow and average values over time and points. The ease of operation is significantly enhanced by the Testo Smart App, which not only streamlines the configuration and management of data but also transforms your smartphone into an auxiliary display, augmenting the user experience.

Key Features
  • Air flow velocity range: 0 to 30m/s
  • Air flow velocity accuracy: ±(0.03 m/s + 4% of m.v.) (0 to 20 m/s) ±(0.5 m/s + 5% of m.v.) (20.01 to 30 m/s)
  • Air flow velocity resolution: 0.01m/s
  • Temperature range: -20˚C to 70˚C
  • Temperature accuracy: ±0.5˚C
  • Temperature resolution: 0.1˚C
  • Volume flow calculation
  • 820mm telescopic probe
  • Point and timed mean values
What’s Included
