Specification:
The softening point determines a disk of the sample held within a
horizontal ring is forced downward a distance of 25.4 mm under the mass
of a steel ball as the sample is heated at a prescribed rate in a water
or glycerine bath.
The Automatic Ring and Ball Apparatus is an innovative
microprocessor controlled automatic tester which is used to determine
the softening point of bituminous materials using water or glycerol as
the heating fluid.
The softening point is taken by two suitably positioned light barriers and the temperature is measured by sensor.
A software permits to select the test method and the test parameters,
run the test automatically, store, retrieve and print data, diagnose and
calibrate the instrument.
Additional cooling system, permits to quickly cool down the sample
allowing to handle the glassware and to perform number of tests during a
day by reducing the dead times between consequent analysis.
A uniform temperature distribution in the vessel is maintained by a
magnetic stirrer, equipped with an adjustable speed control system and
the temperature gradient is strictly maintained during the test the electronic system conforming to the relevant standards.
The apparatus consists of a heater, cooling system, electric lifting
system, and magnetic stirrer with speed control, temperature probe,
glass beaker, ring and ball support, brass ring with steel ball and ball
centering guides, light barrier system, microprocessor system and large
graphic display with touch screen, RS 232 C port for PC or printer.
Power: 750 W
