SYD-0613A/SYD-0613

Automatic asphalt breaking point tester
It is suitable to determine Fraass Breaking Point of bituminous materials.
The tester includes two part they are model HWY-15 low temperature circulation constant bath and breaking point main unit.

Manual asphalt breaking point tester

Used for determining the breaking point of solidandsemi - solid bitumens. The Fraas Breaking Point is the temperature at which bitumen first becomes brittle, as indicated by the appearance of cracks when a thin-film of the bitumen on a metal plaque is cooled and flexed in accordance with specified conditions.
The instrument is composed of outer cylinder, temperature preservation cylinder, thermometer, lower plate, upper grip, fixing rod, base, guide rail, sweeping block, handle, steel sheet and so on.
The temperature preservation cylinder is a double layer glass cylinder. It is used to
place the dry ice and ethylalcohol mixtures. It is the cooling unit.
The lower plate and upper grip are metal sheets.
The fixing rod and movable rod are made of fabroil.
The base, guide rail, sweeping block and handle are used to changer the relative position of fixing rod and movable rod to make the sample sheet bending.
