makroXtens®

The makroXtens is a versatile high-accuracy extensometer operating on the contact principle. Ideal for tensile, compression, flexure and cyclic tests on metals, plastics, composites and many other materials. 

Advantages of the makroXtens

• Standard extensometer in the metals, plastics and automotive industries, with an installed base of over 2.500 systems
• Accuracy class 0.5 according to EN ISO 9513
• Maximum error +/-­ 1µm in differential movement measurement between two measuring points in a range from 20 µm to 200 µm, completely satisfying the additional requirement to ISO 527­-1 (2011)
• makroXtens is calibrated from 20 µm measurement travel in Class 0.5
• Can be used up to specimen break, even with high forces and brittle specimen material
• Compression and flexure tests can be performed simply by changing the sensor arms
• Measuring system is automatically tracked into the optimum position between the specimen grips - maximum measurement travel is always available

• The combination of the videoXtens transverse strain extensometer with the makroXtens provides 
  an ideal contact/optical strain measurement system for the metals and automobile industry
• videoXtens non-contact, high resolution transverse strain measurement allows determination 
  of r-values to ISO 10113
• The width can be determined at one or more locations (measuring lines). This allows measurement 
  of offset yields in tensile tests to ISO 6892-1, together with r & n-values to ISO 10113 and ISO 10275
