|K80020 Constant Temperature Ductility Machine
Standard Ductility Testing Machine Three-speed apparatus 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.
Constant Temperature Model Similar to the standard Ductility Machine, but equipped with a solid state, thermostatically controlled bath and circulator to control temperature within ± 0.9°F (±0.5°C) in the range of 35-90°F (1.7-32.2°C). Circulant water is directed through stainless steel tubes beneath a false bottom in the trough to provide efficient heat transfer. Supplied with three standard brass briquet molds and brass base plate. See K80040 for information on force measuring adapters and molds.
