Test equipment which permits smoke or tear gas grenades to be detonated iors within an expansion chamber portion of the test equipment. The smoke or gas is then channelled through an opacity monitor which is capable of accurately measuring the volume of smoke or gas produced by the grenade. A borescoping system in the expansion chamber permits operating personnel to accurately check the duration of the smoke or gas emmission using external timing devices. After testing the smoke or gas is ducted through a high efficiency filtering system so that when exhausted into the atmosphere it is at a contamination level acceptable to federal and local air quality standards.
