Main features

Smart automatic and connected concrete Power and Control System for standard failure testing.

AUTOMAX PRO-M is CONTROLS’ new top-of-the-range Compact-Line compression machine and is the first choice for automatic standard failure tests and advanced concrete mechanical properties assessment. 

  • Huge boost in efficiency and error elimination: LinK-LAB – Integrated testing station solution for seamless connection and data inputs from many ancillary devices for dimensional measurement, weight, bar code, etc.
  • Fully automatic – time saving: Full test-cycle automation maximizes productivity and ensures tests are performed accurately according to pre-set methods, eliminating operator variables.
  • Highly accurate and energy saving: Our DC motor technology quietly and efficiently delivers super accurate load control at both low-speed and low-loads.
  • Intuitive, quick and simple operation: The integrated control system features an intuitive 7” color graphical display, which works like a tablet or smart-phone, and makes AUTOMAX PRO-M quick and simple to operate.
  • Standards compliant – peace of mind: Automatic performance of Elastic Modulus tests according to the main International Standards with automatic calculation of tests results.
  • Advanced: Allowing the execution of displacement-controlled tests on beams, notched beams, round or square slabs
General description
General description
