Non-contact Concrete Shrinkage Deformation Tester—Model NES

Product Introduction

     Used to measure the free shrinkage deformation of concrete at any time after self-forming, and can also be used to determine the shrinkage and expansion deformation of concrete in an unconstrained state.

Execution Standards
