Automatic ring-and-ball apparatus
Automatic apparatus for determining the softening point of bitumens with optical detection of ball touchdown.
- 24-month warranty and spare parts from stock
- Commissioning, staff training and methodological support
- Assistance with equipment certification as part of your laboratory
Description
The apparatus automatically determines the softening point of bituminous binders by the ring-and-ball method: two samples in brass rings are heated in a beaker at the standard rate, while optical sensors detect the moment the ball touches the reference plate.
A magnetic stirrer and precise control of the 5 °C/min heating rate eliminate the subjectivity of visual reading. The results for both samples and their mean value are shown on the display and stored in memory; data are transferred to a PC via USB.
For softening points above 80 °C a glycerol bath is used — the mode switches automatically with recalculation of the detection threshold.
Features

- Heating rate of 5 ± 0.5 °C/min with PID control
- Water and glycerol bath modes
- Magnetic stirrer with speed stabilization
- Memory for 200 tests, USB interface
- Set of rings, balls and centring guides
