Device for determining frost depth and density

摘要

A hand held device (12) having a forward open window portion (14) adapted to be pushed downwardly into the frost on a surface, and a rear container portion (22) adapted to receive the frost removed from the window area. A graph (FIG. 4) on a side of the container enables an observer to determine the density of the frost from certain measurements noted. The depth of the frost is noted from calibrated lines (28) on the sides of the open window portion (14).
