General description
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 PT 100 sensor placed in a middle position. During operation a magnetic stirrer with adjustable speed assures temperature uniformity in the vessel. The temperature gradient is strictly maintained throughout the test by the electronic system conforming to the standards.

Safety features
The hot plate is automatically cut off at the end of the test cycle. The apparatus is however fit with an emergency stop button. The test is automatically interrupted in case of probe failure or not correctly positioned. The hot plate is not damaged or affected by possible water or glycerol leakages or by the beaker failure.
Note:
Standard manual operated apparatus is also available. See Standard ring and ball apparatus.
