Softening Point Tester :

RKA-5

• Ring-and-ball softening point tester
• For samples without sharply defined melting points
• Suitable for measuring bitumen
• Automatic assessment of results according to the requirements of the standard

The ring-and-ball softening point tester automatically determines the temperature at which a substance attains a particular degree of softness. It is used for samples without sharply defined melting points, which become softer and less viscous as the temperature rises.

The RKA 5 with its different ball-centering and dispensing devices is used for bitumen.

Key features

Benefits at a Glance

• Temperature-heating rate chart for conformity check of each test
• Multi-point temperature calibration
• Provision against the erroneous detection of air bubbles
• Automatic assessment of results acc. to the requirements of the standard
• Statistical and database functionality
