Bellstone Ring & Ball Apparatus

The BELLSTONE Ring and Ball Apparatus is a modernized tool for determining the softening point of bituminous materials. Featuring a compact and user-friendly design, it includes a magnetic stirrer and digital temperature display, allowing precise heating control via an adjustable knob. Operating on a 220V, 50Hz single-phase AC supply, each unit comes equipped with a heat-resistant glass bath. This apparatus is essential for laboratories and quality control in construction, providing accurate measurements of the temperature at which a steel ball sinks through bitumen under standardized conditions. Its improved aesthetics and functional upgrades enhance usability and reliability in asphalt and road material testing procedures.
