ASP-5 Automated Softening Point Tester

The ASP-5 Softening Point Tester automates the softening point test by Ring-and-Ball method (ASTM D 36) for bitumen and similar substances. A photoelectric device with a wide light beam is employed to assure a reliable automatic detection of softening point. The unit detects the falling ball even if the ball falls with some angle. Exact temperature rise rate can be attained not only with water bath, but also with glycerin bath by the precise heater control. Equipped with a safety shutdown.

  • Softening Point Testing per ASTM D 36
  • Photoelectric Sensing Mechanism
  • Wide Zone Detection


Easy Operation: Just set up the specimen, determine the bath liquid type, and press the START key; all the rest of the test procedures such as heating, softening point detection, and heater cooling are performed automatically.

Exact Temperature Rise Control: Exact temperature rise rate can be attained not only with water bath but also with glycerin bath by the precise heater control.

Reliable Falling Ball Detection: Thanks to its wide light projector and wide light receiver, the ASP-5 detects the falling ball even if the ball falls at an angle.

Safety Mechanism: Generation of harmful vapor from overheated glycerin is prevented by the safety shutdown.

Calibration Capability: By simply setting a traceable thermometer right next to the PT-100 temperature sensor and running a test to record and compare the two temperature readings, the user can easily carry out a traceable temperature calibration.

Compact Design: The test head unit can be stacked on the control unit and is also small enough (only 23cm in width) to be operated inside of a fume hood.
