Its function is based on the constant heating method . One Sensorpair , consisting of two needles, is inserted one above the other in the sapwood. The upper one is containing an electric heater which is continuously consumed with constant power. The measured temperature difference gives a direct conversion to sapflow density.

Show Sensors

Dendrometers are often used to measure the stemdiameter or the growth of the stem. Together with sapflow sensors and the Water Flow Software (Waflos) you will get more information about transpiration.
