Product Application

   Used to determine the migration coefficient of chloride ions in concrete under non-steady-state migration to evaluate the concrete's resistance to chloride ion penetration and measure its impermeability (density).

    This product can perform tests using the electric flux method, 30V constant voltage diffusion coefficient method (transportation standard), 5～60V variable voltage diffusion coefficient method (national standard), as well as constant current method tests, facilitating comparative research experiments.
