Plant physiology

Plant physiology

In this category we offer measurement solutions for the measurement of sapflow as well as for tree-growth. Our sapflow-sensors are based on the development of Dr. Andre Granier, INRA Nancy, in the 1990s. In the meantime we sold more than 10.000 sensors with different design (up to 3 thermocouples per needle, different needle-lengths, different length of heating-zone...) to be used no longer not only for pine-trees. Together with the ITC, Wageningen, within the last years we developed the CHD/NTG- (natural temperatur gradient) methode to compensate errors through changes in the way the sensors are heated.

The use of dendrometers and PAR-Sensors give the complete picture of the status of the plant. Dendrometers are quite often used together with our Scatter100 system that allows wireless signal-transmission even in the forest. Scroll down for more information.
