testo 440 Hot Wire Kit

  • Intuitive: clearly structured measurement menu for volume flow and parallel determination of air velocity, volume flow and air temperature in ventilation ducts

  • Convenient: integrated telescope that can be extended to 0.85 m, with scaling, makes it easy to carry out measurements

  • Reliable: absolute pressure compensation, internal data storage and USB port for data export

  • As multifaceted as your challenges themselves: the air velocity and IAQ measuring instrument can be expanded with a large portfolio of digital probes

Product Description

Kit for carrying out measurements in ventilation ducts: the testo 440 air velocity and IAQ measuring instrument and the hot wire probe (Ø 9 mm) including temperature sensor are all safely stowed away in the case. So you can get down to work straight away!
