  Depressing the Reset Button on Digital Counter starts the series of blows programed for the compaction. With each revolution of the motor driven fly-wheel, the lever-multiplied scissor-action Grabber picks up the rammer while it rests on the specimen.

As the rammer is lifted, it is circulated for distribution of the blow. When the Grabber has risen the speified distance (12 in. or 18 in.) it releases the rammer for a free fall drop. Thus, a drop is relative to the specimen elevation every time, and adjustments between specimen layers are avoided. After the final blow in the series, the Programing Counter automatically stops the compaction.

Three models are available:
STCB-1-4: Comes with one 4" dia. mold and related rammer
STCB-1-6: Comes with one 6" dia. mold and related rammer
STCB-1-46: Comes with one each, 4" dia. and 6" dia. molds and related rammers

Add $250 for 220V/50Hz operation.
