Patent ID: 7681467

Claim:
A rotary sampling apparatus for sampling the installed density of an insulative material installed adjacent to a building structure by obtaining a sample length, said apparatus comprising: (a) a generally cylindrical sampling tube open on its distal end, wherein the length of the sampling tube is greater than the sample length; (b) an end wall that has a surface approximately perpendicular to the longitudinal axis of the tube, the surface including at least one exhaust port outside the sampling length, said exhaust port adapted to both permit the unobstructed egress of air therethrough, and to exhaust air directly from the port into the ambient; (c) at least one serration on the distal end of the sampling tube, wherein the at least one serration is configured to cut into the installed insulative material and to prevent breaching the adjacent building structure; and (d) a drive attached to the proximate end of the sampling tube for aiding in sampling, wherein the drive includes a quick disconnect between the drive and the sampling tube.
