Transversal Extensometer Series MFQ-H

The self-supporting, hand-clamped, transversal extensometers MFQ-H are designed for measuring plastic strain ratio (r-value) in sheet (metal) testing or round samples.

Model MFQ-H extensometers are applicable for testing to ISO 10113 and ASTM E517.

These extensometers are available with one measuring location or as is available with one single measuring location or as averaging unit with two measuring locations.

MFQ-H models are equipped with easy exchangeable, fixed B0 -stops for fixed initial width of the specimen.
The stoppers are easy and quick to change without any tools.

These extensometers are self-supporting on the sample. As the test sample is pulled, the contact edges follow the part of the sample they were mounted on, measuring lateral strain on the sample at the same location throughout the test.

The MFQ-H are compatible with MFL, MFX automatic axial extensometers and often used simultaneous with axial clip-on extensometer model MFA.
