This Koehler standard ductility testing machine is a three-speed apparatus which pulls briquets of bituminous materials apart at a uniform speed while immersing them in water. As many as three specimens at a time can be tested at speeds of 0.25, 1 or 5cm per minute. A synchronous direct motor drive unit maintains constant speed without vibration. Drive unit rides on a bronze lead screw mounted above the water level to prevent agitation of water and premature rupture of specimens. A traveling pointer indicates the position of the carriage against a linear centimeter scale on the trough. Elongation capacity is 150cm, with automatic carriage stop. Polished stainless steel trough has overflow connection. Equipped with bronze gears and solid brass components to prevent rusting.
