B070N1 Automatic Digital Ring and Ball Apparatus


This high technology 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 fan cooling system enables to quickly cool down the samples, allowing to perform many more tests per day.
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.

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.
