The Convex Densiometer is used to determine the thinning of a canopy, spacing for replanting, or when gauging habitat suitability of a particular area. It works similar to a periscope and has a spherical mirror to reflect the sky above.
A cross-shaped grid with 24 inch squares on the densiometer help the user plot the overhead reflection. The densiometer also features a built in levelling bubble, so it can always be used correctly. This is important, because the user must have the unit level to use it properly. The Convex shaped Densiometer helps to keep only the sky in the reflection, so choose the Convex Densiometer over the Concave Densiometer for the larger sample reading.
