The MFA2 linear strain gauge is suitable for virtually all tests above an initial instrument measuring length (Le) of 25 mm.
EXTENSOMETER max stroke 2 mmThe MFA2 linear strain gauge is suitable for virtuallyall tests above an initial instrument measuringlength (Le) of 25 mm. Its measuring accuracyexceeds all requirements set down by standard ENISO 9513. Its design, which has been tried andtested over many years of use, guarantees a highlevel of reliability and a long service life, even underdifficult operating conditions. The MFA is particularlysuitable for determining the module of elasticity,proof stress and ultimate strain. The MFA is fast,straight forward and easy to use, and thereforeenables large numbers of tests to be carried out.
