ArborElectro Impedance Tomograph
- For detecting size and location of active fungi attacked regions
- It works based on electric resistivity measurements
- Up to 32 sensors around the trunk
- Seasonal and daily changes can be visualised (view the presentation here)
- Resistivity increases/decreases if there is a change in the ionic concentration
- Fungi attacks even in very early stages may be determined
Place the resistivity meter onto the tree.
Measure the circumference and decide the proper shape (circular, elliptic or irregular). Place the electrodes onto the tree at the proper positions or measure their positions. Enter the data to the computer.
Start the measurement on the computer. During the measurement do not touch the tree. Do not measure other conditions parallel to the resistivity measurement.
Choose triangulation parameters and run the iterations. The program will calculate the resistivity map of the selected cross section.
