Brittleness tester

temperaturefor rubberlow temperature

Tests at low temperatures permit to evaluate the crystallization effects and to compare viscoelastic properties of rubber and rubber-like materials at low temperatures. Temperature Retraction and Brittleness Point tests are useful for the selection of materials suitable for low-temperature service. The structure of the Low Temperature Check permits the installation of arrangements for TR and Brittleness point tests. The structure includes the common parts required for low temperature testing: • 5 litres stainless steel bath for cooling liquid • Heat exchangers for bath cooling & thermal resistance for bath heating • Temperature controller with 0.1°C resolution • Stirrer for bath homogenization • Electronic card for the complete control and usb port for PC connection • Safety devices: independent bath overheating controller, thermal switch, safety pushbutton. Key Features The instrument has been specially developed to automate test execution, minimize operator influence on results and ensure full compliance with safety requirements. The most important features are: • Automatic temperature adjustment based on the selected test procedure • Possibility to configure the instrument for the execution of TEMPERATURE RETRACTION (TR) and / or BRITTLENESS POINT tests • Automatic execution of the entire test cycle in compliance with international standards • Automatic recording of retraction curves • Saving of curves and numerical results in the standard Gibitre SQL database • Possibility of configuring the instrument for cooling via liquid nitrogen tank and refrigeration unit • CE labelling
