 Floor Standing Soils Resilient Modulus Testing System   STTX-2   $165,000.00      
 
 
  Description
  This is a highly flexible, floor standing, servohydraulic universal testing system that will never become obsolete. When equipped with computer, software and other appropriate accessories, this system can perform Soils Resilient Modulus testing either manually or fully automated.

This system is an updated version of the machine and software originally used by SHRP to develop the Soils Resilient Modulus protocol, and has successfully completed several thousand tests.

The flexibility of the loading system and standard software packages allows it to perform virtually any other testing up to the 100kN maximum rated load. Optional temperature or T/H chambers, asphalt testing fixtures, compression platens and triaxial cells are available to create a complete testing system. A separate hydraulic power supply may be selected from a wide range of capabilities, including air or water cooled, remote location, acoustic enclosure or quiet pump.

NOTE: Each system is individually configured based on your requirements, so listed price and configurations should be considered only as a guide.
