Tree Care & Tree Inspection
Recognize warning signals early enough


How healthy is the tree?

In the context of tree care and tree inspection our instruments help to detect inner defects at an early stage and to ensure the public safety. That way you can take steps to avoid personal and material damages in parks, alleys and forests.

The VTA method (Visual Tree Assessment) helps to detect defects by outward manifestations of the tree and therefore it ensures the correct application of our instruments. By means of this method (visual assessment) arborists, tree inspectors and experts are able to identify in time dangers due to immanent tree failure. That way they can take the right measures early enough to prevent damages to persons or property.

The VTA method...

In this fields our innovative wood testing systems will assist you:

  • IML Micro Hammer
    (Sound speed measurement)
    Easy and fast verification of defects yet in early stages of damage
  • IML Resistograph Systems
    (Drilling resistance measurement)
    Accurate identification of defects and measurement of the thickness of the residual wall
  • Fractometer
    (Bending & compression strength measurement)
    Evaluation of stability and strength of wood using a wooden core extracted with the increment borer
  • IML-Measuring Table
    (Analysis of annual rings)
    Analysis of wooden cores of trees and information about the structure of the annual rings, growth and wood decay

The measurement methods of our test instruments are scientifically proven. Scientists and specialists recommend them as objective and reliable examination methods.
