General description
General description

The compact UNIFRAME Universal Automatic flexural and compression tester is suitable for any kind of test that requires load and/or displacement control such as CBR, Marshall, Quick Undrained Triaxial, Flexural, Unconfined compression and many more.

This model features a robust and compact two-column frame which is fitted with an upper crossbeam that can be set at various heights depending on the accessories to be used. The  jack is driven by a DC motor controlled by the microprocessor.
The load jack, DC motor and controls are housed in an ergonomic cabinet. Closed-loop control ensures reliable test execution both with displacement and load applications. No external transducer is required for displacement measurement. Sample failure is detected automatically and stops the test. Alternatively this feature can be disabled and a travel or time limit can be set instead.
Software user-interface allows the setting of speed/load and travel/load limits, data format download and graph settings, and saving of pre-set test procedures (up to 10 profiles can be saved in the internal memory of the machine). 
The firmware allows performance of up to four transducer calibrations (two load cells and two potentiometric linear transucers), saving data onboard.  A real-time test graph and transducer data are displayed on the touchscreen. The user-interface is a large touchscreen graphic display supplied with a stylus pen.
The front panel is fitted with an emergency button for prompt stopping of the machine.
Test data can be stored on a USB pen drive or downloaded through a LAN communication port in Controls, txt or ASCII format.
All accessories have to be ordered separately.
