Annual Ring Analysis
Identifying the growth characteristics of trees
Recognize growth behavior of trees

The growth behavior of trees provides important information about climatic conditions and temporary or continuing changes in the living conditions of the trees. In order to recognize and correctly measure the annual ring structure of even weakly growing trees, every last detail is important during the preparation and evaluation of the wood samples.

With the IML Measuring Table you can evaluate the annual rings of wooden cores and tree discs quickly and easily.

  • Exact evaluation of annual rings of core samples and tree discs
  • Identification of disturbances of development and growth as well as weak growth
  • Illustration and assignment of changes, dysfunctions or weak points
  • Findings about the vitality of a tree
  • Possible conclusions on environmental influences

    The growth behaviour of trees provides important information about climatic circumstances and temporary or persistent changes of the environmental conditions. In order to correctly identify and measure the annual rings of trees with small growth, every detail of the processing and evaluation is important.

  • IML Fractometer II
    IML Fractometer II

    The Fractometer II is a mechanical measurement instrument to determine characteristic values of bending and compression strength of wood.

  • IML Fractometer I
    IML Fractometer I

    The Fractometer I is a pocket-size testing machine for wood. It puts bending load on a core sample that was taken with the increment borer.
