The Spherical Crown Densiometer is an essential tool for forest canopy measurements and density assessments. This Model-A instrument features a convex spherical mirror housed in a durable wooden case with brass fittings. The densiometer allows for accurate measurement of forest canopy coverage through systematic dot counting within its grid system. Perfect for forestry professionals, researchers, and environmental scientists, this precision instrument comes with clear instructions for obtaining percent canopy readings from four cardinal directions. The compact design makes it highly portable for field work while maintaining professional accuracy. Each unit includes detailed operating instructions mounted inside the protective case lid, explaining the proper 12"-18" positioning and dot counting methodology. The instrument provides reliable overhead canopy measurements by enabling users to count dots equivalent to quarter-square canopy openings. Its robust construction ensures longevity in field conditions, while the protective wooden case offers safe storage and transport between measurement locations.
