Used to determine the strain deformation characteristics of concrete specimens. It comprises two steel rings for clamping to the specimen, two gauge-length bars and a spherically-seated lever unit. Supplied without dial gauge or strain transducer to be ordered separately (see accessories).
They can be suitable to measure both the axial and the lateral deformation, needed respectively to determine the elastic modulus and the Poisson ratio.
Available models:
Note: To grant full compliance to the relevant EN, ASTM, ISO and BS standards, it is necessary to use an extensometer/compressometer together with the upgrade C125M, which allows to perform load/ unload cycles.
