nDendrometerAn instrument to measure the height and diameter of trees.
Century Dictionary and Cyclopedia
ndendrometerAn apparatus for measuring the heights of trees. It consists essentially of a square board pivoted at one corner to a stake set up at a known distance from the tree to be measured. A sight on the board enables the operator to fix the instrument on a level with the base of the tree; then on sighting the top of the tree its height is ascertained from the position of a plumb-line and scale on the face of the board.
