LBTC-323 Butterfly Extensometer

The rebar mechanical splice residual deformation measuring instrument is primarily used to measure the residual deformation of rebar mechanical splice joints. It consists of two high-precision electronic extensometers with consistent sensitivity, symmetrically mounted to directly measure the average deformation on both sides of the specimen, ensuring accurate measurement results. It complies with the standard requirements specified in JGJ 107, “Technical Code for Mechanical Splicing of Reinforcing Bars.”
