EU – Project CHLORTEST G6RD -CT – 2002 – 00855

CEN TC 51(CEN TC 104)/WG12/TG5

This tester is used to determine the permeability resistance to chloridion of concrete by NT BUILD 492 Mehtod (by testing the Chloride migration coefficient from non-steady-state migration experiments), thus to provide reference for the concrete structure design and service life assessment, also provide basis for concrete mix design and concrete structure quality assessment. it’s suitable to test the lab made specimen with max aggregate size not over than 25mm or the cored sample from concrete structure.


  • 32-bit embedded ARM core with high processing speed
