We offer a complete product range of Spherical Crown Densiometer, Soil pH Meter and Soil Testing Equipment
Accurate, one person measurement of tree canopies. Measure forest overstory density from unobstructed sighting positions. The instrument uses a spherical-shaped reflector mirror engraved with a cross-shaped grid of 24 quarter inch squares. To take readings, hold the instrument level, 12" to 18" in front of body and at elbow height. Assume four equi-spaced dots in each square of the grid and systematically count the dots equivalent to quarter-square openings. Multiply the total count by 1.04 to obtain percent of overhead area not occupied by canopy. The difference between this and 100 is an estimation of overstory density in percent. Units are housed in a 3" x 3" x 1" thick walnut case with operating instructions permanently affixed to the lid. A leveling bubble is also included for accurate positioning during estimations.
