Automatic Ring and Ball Apparatus

This advanced microprocessor controlled automatic tester is used to determine the softening point of bitumen using water or glycerol as heating fluid.

The softening point is taken by two suitably positioned light barriers and the temperature is measured by a PT100 sensor placed in a central 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 which conforms to the Standards.

81-PV0143: Automatic ring and ball apparatus. 230 V, 50-60 Hz, 1 ph

Main features:
  • Microprocessor control
  • Automatic programmable test sequences for water or glycerol
  • RS 232 serial port for PC or printer
  • Large graphic display 240x128 pixel
  • Memory up to 50 tests

Safety features
The hot plate is automatically turned off at the end of the test. The apparatus is also fitted with an emergency stop button. The test is automatically interrupted if theprobe fails or it is not correctly positioned. The hot plate will not be damaged or affected by possible water or glycerol leakages of water or glycerol, or if the beaker breaks.
Standard ring and ball apparatus is used for determining the softening point of bituminous materials.

The test has to be performed using the specific liquids and the suitable hot plate listed within the accessories. We propose three hot plate solutions:
  • 10-D1402/D Standard hot plate, 185 mm dia., 1500 W. More economical solution thus conforming to ASTM standards.
  • 81-B0145/C1 Hot plate with centering/protection device for 81-B0145 Ring and Ball apparatus. More professional solution.
  • 81-B0145/D Hot plate with magnetic stirrer, conforming either to ASTM or to EN 1427 Standards which require the water stirring for more temperature uniformity.
