Non-contact shrinkage deformation tester

Purpose:
It is used non-contact displacement measurement technology, after molding shrinkage deformation of concrete specimens are fully automatic real-time monitoring, through data processing, can be determined after initial setting or close to the initial setting free shrinkage deformation of early age concrete early age can also be used for unconstrained condition isolated wet autogenous shrinkage deformation under the condition of determination of the exchange
