Testo 440 - Hot Wire Kit (Ø 0.35")

Brand: Testo

This Testo 440 kit is great for carrying out measurements in ventilation ducts.

The Testo 440 air velocity and IAQ measuring instrument and its hot wire probe (Ø 0.35") with temperature sensor can all be safely stored in the included case.
Features
  • A measuring instrument for all climate-related parameters
  • Intuitive: clearly structured measurement menu for volume flow and determination of air velocity in ventilation ducts
  • Convenient: integrated telescope that can be extended to 0.85 m, with scaling, makes it easy to carry out measurements
  • Extendible with a wide range of probes
  • Analytical software for creating professional reports and measurement data management
  • Digital probes eliminate any additional measurement uncertainty of the measuring instrument
