Buyer’s Guide 2012 Update: Testing and Quality Control Extensometer Meets Accuracy Class 0.5 in ISO 9513
The makroXtens high-accuracy contact extensometer for both stand-alone and fully automatic testing systems was specially developed by Zwick for performing tensile, compression, flexural and cycling tests on metals, plastics, composites and other materials.

This new instrument satisfies the requirements of Accuracy Class 0.5 specified in ISO 9513, as verified from 20 µm in the calibration report.
With the makroXtens, the maximum error in differential movement measurement between two measuring points in the range of 20 µm to 200 µm is only ±1 µm. This completely fulfills the requirements of ISO 527-1 (2011) and delivers the accuracy necessary for operations such as measuring Young’s modulus on plastics. Longitudinal strain on specimens is recorded in the elastic and plastic deformation ranges throughout the tensile test range up to specimen break, including under high tensile forces and with brittle materials.
The new makroXtens is available in P and HP versions, each with three sensor-arm lengths (300, 450 and 600 mm). The HP version offers higher levels of resolution and approval for closed-loop strain-rate control to ISO 6892-1 (2009) Method A(1) and ASTM E8-09 (Method B), and its intelligent tracking device provides greater measurement accuracy, particularly in the initial measuring range, along with optimized handling.
