The Testo multifunction probe is used with for 435 Series to determine the flow velocity and volume flow in ventilation ducts or at ventilation outlets. It is particularly suitable for low and medium flow velocities up to 20m/s. This probe can also measure temperature and humidity simultaneously. The hotwire probe is equipped with a telescope, which can be extended to a maximum length of 745mm.
