Identify Decay Inside Tree Using PICUS Sonic Tomogram
PiCUS Sonic Tomograph is used for tree risk assessments in order to measure the thickness of the residual wall of trees with internal defects such as cavities or decay non-invasively. Most often the PiCUS sonic tomograms are recorded near ground level of trees. However, acoustic tomograms also reveal important safety information about the breaking risk near branch wounds and above ground cavities.
How to use it?
1. through visual inspection
2. Select measuring Level and measuring point
3.Mount equipment on the tree
4. Record geometry of measuring level
5. Sonic measurement
6.Calculation
