Spherical Densiometer, Concave
Product Code: SDN-CC
The Spherical Densiometer, Concave is a precision forestry instrument used to estimate forest canopy cover, canopy closure, and overstory density. It features a convexly engraved grid on a concave mirrored surface, allowing users to estimate the percentage of overhead canopy by counting the reflected grid intersections covered by vegetation. Compact and portable, the concave spherical densiometer is widely used by foresters, ecologists, fisheries biologists, hydrologists, and environmental scientists for habitat assessments, riparian monitoring, wetland evaluations, and forest inventory studies. The concave model provides a wider field of view than the convex version, making it particularly useful for evaluating larger canopy areas from a single observation point.
- Measures forest canopy closure and percent canopy cover quickly in the field.
- Concave mirror provides a larger reflected viewing area, allowing more canopy to be assessed from a single location.
- Permanently engraved grid ensures long-term measurement accuracy.
- Built-in bubble level helps maintain proper instrument orientation.
- Compact, lightweight design fits easily into a field vest or backpack.
- Rugged construction suitable for demanding field conditions.
