Electronic automatic asphalt penetrometer

STANDARD: EN 1427, ASTM D36

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. 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. It is used to test the  temperature of asphaltum when asphaltum softens

and drops 25mm under the heating conditions.  Computer-controlled temperature rising speed, data  checking, data saving and data processing.
