Ring and Ball Softening Point Apparatus

The softness of bitumen depends, amongst other factors, on the substance temperature, the more the temperature increases, the more increases the softness of the bitumen. The unit consists of a pyrex beaker, brass frame, two tapered rings, two ball centering guides and two balls.

This “high tecnology” digital microprocessor tester, designed and manufactured by Matest, automatically determines the softening point of asphalts and pitches.
Two laser sensors detect the balls fall determining the softening point.
The bath temperature is measured by an electronic system maintaining the gradient (5 °C/min) as specified by the Standards.
A magnetic stirrer with electronic speed adjustment from 0 to 160 rpm also ensures a uniform temperature in the vessel during the test execution.
The touch-screen graphical interface allows an easy set up of the parameters and the immediate execution of the test.
High resolution color display, 1/4 VGA, offers all the functions of a PC for the management and analysis of data, test results, and graphs.
Two test parameters can be selected in the microprocessor menu:
- test on boiled distilled water for softening point from 30 to 80 °C.
- test on glycerol for softening point from 80 up to 150 °C.
Language selection: English, French, Spanish, German, Italian,Polish, Russian, Greek, Portuguese and Dutch.
Available functions: clock calendar, test number, user/custome name, general notes, start/end of the test.
Real time visualisation of the bath temperature, test progress, rpm of the stirrer. - Fully automatic.

The tester is basically composed of:
- Ceramic-glass heating plate with automatic cut off at the end of the test cycle.
- Motherboard with microprocessor, which controls: heater/stirrer, temperature probe, laser sensors, pre-heating phase of the plate, and memorizes all the test parameters.
- Steel balls centering device.

Power supply: 230V 1ph 50-60Hz 700W
Dimensions: 500x350xh550 mm
Weight: 20 kg approx

The softening point is the temperature at which 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 apparatus is a benchtop model which houses the components and a Panel PC with touch screen. A software running under Microsoft Windows Xp permits to select the test method and the test parameters, run the test automatically, store, retrieve and print data, diagnose and calibrate the instrument offering in the meanwhile all the features of Windows systems such as LAN connectivity. Besides, a unique cooling system, not fitted on other instruments permits to quickly cool down the sample allowing to handle the glassware and to perform a greater number of tests during a day by reducing the dead times between two analysis. The apparatus is suitable also to test coating mixtures and other materials different from bitumen.
