Enabling better global research outcomes in soil, plant & environmental monitoring.


DYNATIM™ is a sensitive system recording even minimal movements of trees - or wooden constructions.

Wind is by far the dominating mechanical force on trees. Studying the dynamic behaviour of trees helps researchers to understand their mechanical design and conditions of failure.

Continuous measurement and recording of natural and artificial loads (wind, pulling), fibre strain and inclination of trees or timber structures.

Graphical and numerical analysis of dynamic behaviour of tree or structural timber.
