DENDRO 2003 Tree-Ring-Workstation

The DENDRO 2003 equipment is the third generation of densitometrical instruments developed by WALESCH Electronic. Made for density studies on the wood of forestry products, e.g. fast-growing trees, particle board and paper.

Reconstruction of local and worlwide climatological conditions over thousands of years. Evidence of natural and man-made environmental changes in forests, lakes and oceans.

- DENDRO 2003 can be used in dendrochronology, forest research, wood technology, sedimentology, zoology and photography for the solution of climatological, ecological, technological and historical problems.

- DENDRO 2003 is a technically mature instrument based on scientific and ergonomic principles.

- DENDRO 2003 is particulary suited to densitometrical analysis of structurally heterogeneous objects in the microns to 300 millimetre range.

- DENDRO 2003 has proven its usability, particulary for analysis of annual structures such as tree rings, varves and corals.

Main Features

  • Analysis of X-ray film in transmission light.
  • Analysis of surfaces in incident light.
  • Fast, precise and repeatable positioning of objects on the positioning table. (A triple-axis joystick moves the table over a large X and Y range of 300 x 170mm).
  • Projection of objects on a large rotatable screen with 10, 25 or 50-times magnification. (other magnification available on request)
  • Automatic and manual data acquisition.
  • Logical and user friendly control panel design allow easy and efficient handling.
  • Data recording on a computer.
  • Digitalization and convertion of the recorded density values to graphic formats for easy data-processing, data-management and data-comparison.
  • Electrical object focusing and brightness control.
  • Photo sensors of variable size with inclinable axis.
  • Forward and Backward table movement during data acquisition.
  • Manualy operated sliding potentiometers to record structures with small density deviations.
  • The application in dendrochronology is described in the book: "Tree Rings" by Prof. F. H. Schweingruber; Reidel/Kluver, Dordrecht, Boston, Lancaster, Tokyo 1988.

Photo sensor for density measurement

  • The photo sensor is divided into segments which can be calibrated individually.
  • Each segment can be toggled on and off to define the measurement column length. (This may be useful to ignore irregularities on samples.)
  • The measurement column length is indicated on the screen.
