ABSTRACT:
An apparatus, for determining the degree of tackiness of a surface of a body, comprises a closed chamber with inlet and outlet openings; a support for the body within the chamber; a fan for providing an airflow directed toward the surface of the body within the chamber; a powder dispenser for releasing powder into the path of the airflow upstream of the body surface, the powder being adapted to be carried by the airflow thereby to permit the powder to impinge against the body surface; whereby the amount of powder adhering to the body surface after a period provides a measure of tackiness of the surface.
