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 suitable for bitumen, waxes, adhesives, resins, polymers, road-marking materials and sealing compounds.
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

·         The heating system is spill-protected and in a sealed case for safe operation and easy cleaning

 

Convenient Operation

·         A laser scanner system covers the whole beaker cross-section area. This ensures a very reliable detection of the falling ball.

The smart jog wheel operation system (turn and push) and Pmove®, as an innovative operation platform, make it easy to select one of the pre-set standard programs or choose one of the 20 user-definable settings.
