Bending Beam Rheometer – QualiBBR-1 Features

• Features real-time display of deformation, pressure, and temperature curves.
• Integrated LVDT calibration system ensures quick and straightforward calibration.
• Utilizes a dual cooling system combining Peltier elements and a chiller for fast cooling and high-precision temperature control.
• The chiller connects to the main unit via a hose and is placed separately to eliminate vibration interference during testing.
• Includes a liquid bath with an adjustable-speed magnetic stirrer for consistent temperature distribution.
• Air supply pressure, pre-pressure, load pressure, and air bearing pressure are digitally monitored through the software.
• Equipped with a USB port for easy data export.
• Features overload protection, fault alerts, buzzer alarms, and fault code display.
• Built with a stainless steel base for durability and easy maintenance.
• Test duration is adjustable (default: 240 seconds) to accommodate deformation checks.
• Result calculation times can be set via software (default options: 8s, 15s, 30s, 60s, 120s, 240s).
• Two-stage air filtration system helps maintain testing accuracy by eliminating contaminants.

Bending Beam Rheometer – QualiBBR-1

QualiBBR-1 Bending Beam Rheometer is designed to measure the flexural creep stiffness of asphalt binders at low temperatures. It helps assess the binder’s resistance to cracking in cold conditions. Test results include low-temperature creep stiffness, S(t), and the rate of stiffness change, m(t).
