Automatic Bitumen Softening Point Tester Ring and Ball

Ring and ball apparatus with automatic ball-drop detection and stirrer for determining the softening point of bitumen and modified binders. Used in refineries, polymer-modified bitumen plants and road labs.

Specification

Bitumen in brass rings is heated at 5 deg C per minute under steel balls in a stirred bath, and the temperature at which each ball touches the lower plate is recorded automatically. The tester improves consistency over manual observation. It is used for grading paving bitumen and polymer modified binders.

Features

• Automatic optical ball-drop detection
• Magnetic stirring for uniform bath temperature
• Digital controller with linear 5 deg C/min ramp
• Glass beaker bath with PT100 sensor
• Two-position test head
