Introduction
The UNIFRAME universal automatic flexural and compression tester is a large machine for displacement and load controlled tests. The main advantage of this machine is its high flexibility as a general purpose testing system, ensured by its generous dimensions which allow the placement of an extensive range of accessories, and the software. A wide range of tests can be performed: CBR, Marshall, Triaxial, Flexural tests on concrete beams and tiles, Unconfined compression, punching tests and many more.

Description
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.
This model is equipped with adjustable limit switches, mounted on one column. An handlewheel is used to manually move the the platen during calibration procedure so that the load can be maintained constant with good precision. This facility can be used for the calibration of any load cell present in the laboratory and not only for the one supplied with the machine.
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 transducers), saving data onboard.  A real-time test graph and transducer data are displayed on the touchscreen.
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 LAN communication port in Controls, txt or ASCII format.
All accessories have to be ordered separately.

Data download: using LAN port  (ASCII, TXT or Controls format)
Resolution: 132000 divisions
Sampling frequency: 50 samples/s
Large memory data storage in USB pen drive
