ASPHALT & BITUMEN
Automatic Softening Point
ASTM D36, IP 58, ISO 4625
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 instrument is a benchtop model which houses the components and a touch screen interface. A software running under Microsoft Windows embedded permits to select the test method and the test parameters, run the test automatically, store, retrieve and print data, diagnose and calibrate the instrument.
Enamel finished steel case
Pyrex beaker 1000 ml capacity for sample heating.
Automatic electric lifting device.
Stainless steel sample support for up to two samples.
Two brass ASTM rings, two centering devices and two steel balls.
Variable speed electric stirrer - it can be excluded by turning off a switch on the control panel.
Stainless steel heater.
Cooling system: Integrated brass cooling coil fitted with a solenoid valve is automatically opened by the controller when the test finishes (requires tap water)
PC based controller with colour touch-screen interface.
Automatic softening point detection via optical detector
Software characteristics: selection of the media used during the test, introduction of the test parameter through the touch-screen, selectable cooling time, storage of up to 400 test results and possibility of retrieve and print test reports, LAN connectivity, calibration and diagnostic routines.
