ABSTRACT:
An apparatus is provided to measure the wetting efficacy of certain dust control chemical additives. These additives are commonly sprayed on the dust to control and/or prevent the dissemination of the dust into the atmosphere. The device comprises a plurality of dust collection cylinders, each of which is adapted to retain a dust sample and the particular chemical additive for which testing is desired. A support is provided to support the cylinders and a visual display is operatively associated with the cylinders so as to indicate when the particular additive has completely penetrated the dust and thereby contacted the visual display.
