Spherical Crown Densiometer, Concave and Convex Model.

Helpful when establishing spacing standards in forest thinning and determining light requirements for regeneration. Both models feature a mirror reflector engraved with a cross-shaped grid of 24 quarter-inch squares to delineate a plot overhead. Slightly offset convex model when using so your head does not appear in grid. Walnut instrument case is 3” x 3”. Built-in leveling bubble. Operating instructions included.

A Spherical Crown Densiometer is used to determine thinning of a canopy, spacing for re-planting or when trying to gauge habitat suitability for a particular area.

Measure forest overstory density from unobstructed sighting positions. Also used as an indicator in wetland delineation work.

A Spherical Crown Densiometer works similar to a periscope. The spherical shaped mirror reflects the sky above you to help determine the amount of tree canopy.

A cross shaped grid with 24 quarter inch squares helps plot the overhead reflection.

In order for a Densiometer to be used properly, it must be level. Our Spherical Crown Densiometer features a built in leveling bubble, so the Densiometer can always be used correctly.

The readings from the Convex Densiometer represent a larger sample size than those from the Concave Densiometer.
