Forest-biological measuring and investigation technology
The PiCUS Sonic Tomograph is an instrument to detect decay and cavities in standing trees non-invasively. The result of the measurement is a 2 dimensional map of the apparent sonic velocity in the cross section of the tree. The velocity of sound in wood depends on the health of the wood.
The Treetronic uses electric current/voltage to investigate the tree. The result of the measurement is a 2 dimensional map of the apparent electrical impedance of the tree. Chemical properties of the wood affect the resistivity; most of all: water content, the structure of the cells, ion concentration and others. The chemical properties are changed if decay etc. is in the tree.
The TreeQinetic system is designed to collect data during static tree pulling tests. A static pulling test can be used to estimate the uprooting and breaking safety of a tree. It can also be used to record the sway motion of trees in winds.
The PiCUS Calliper is an instrument to record the geometry of the tomography level quickly and accurately. This geometry data is needed for sonic and EI tomography inspections. It is particularly useful for testing large or irregularly shaped trees.
