Testing Made Easy
To facilitate quick, simple and easy operation, we have developed the Automatic Triaxial Cell. To minimize disturbance to the sample and reduce heavy lifting. We have incorporated innovative pneumatic lift cylinders into the design. These are computer controlled and automatically raise and lower the cell wall to give you complete 360º access to the specimen.
Top mounted LVDT displacement transducers with extension rods enable accurate measurement of specimen deformation and compliance with a range of international standards, including EN 12697 Part 25 Test method B.
