EN 1427


General Description


This advanced microprocessor controlled automatic tester is used to determine the softening point of bitumen using, as heating fluid, water or glycerol.

The softening point is taken by two light barriers suitably positioned and the temperature measured by a PT100 sensor placed in a middle position.

The temperature gradient is strictly maintained throughout the test by the electronic system conforming to the standards.

The apparatus comprises the following parts:

• Heater and magnetic stirrer with speed control
• Temperature probe
• Glass beaker, ring and ball support, test rings and ball support
• Application and centering device of steel balls
• Light barrier system
• Microprocessor system and large graphic display with membrane keyboard
• RS 232 port for PC or printer
• Power: 750 W
• Overall dimensions: 530x300x280 mm
