A field evaluation of a prototype PHS Smoke Inspection Guide was conducted. It was concluded that this type of guide was more reproducible and more adaptable for field use than the printed Ringelmann Chart. Empirical calibrations of the prototype guide were made initially and after little, moderate, and heavy field use. The usability of the guide in field application was evaluated on the basis of interferences, ease of application and maintenance. In all cases the responses indicated little or no undesirable effects.
