The DELTALAB electro-mechanical universal testing machines are used in a wide range of applications in strength of materials for static tests. The test machines accept many types of materials and components as well as complete assemblies and structures.


The EM550 is an industrial design electro-mechanical testing machine with a capacity of 50 kN in traction and compression, adapted for the particular needs of engineering colleges, research and quality control.
Tests may be carried out as a function of speed, stress or strain.
The analogue/digital interface and the software provided with the EM550 form a complete package allowing control, data acquisition and analysis using a PC. The advanced, user-friendly software is presented in toolbox form that demands no particular programming knowledge.
Data analysis and presentation can be effected off-line. Data from current and previous runs may be transferred as ASCII files for use with spreadsheet and other software.
