The ArborElectro Impedance Tomograph is able to detect the size and location of active fungi attacked regions in the trunk non-destructively. It works based on electric resistivity measurements between several sensors around the trunk. The basic measurement principle is that resistivity increases/decreases if there is a change in the concentration of ions between two sensors. Fungi attacks even in very early stages can be determined.

  1. Place the resistivity meter onto the tree.
  2. 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.
  3. Start the measurement on the computer. During the measurement do not touch the tree. Do not measure other conditions parallel to the resistivity measurement.
  4. Choose triangulation parameters and run the iterations. The program will calculate the resistivity map of the selected cross section.
