공기수분침투율측정기 (Model AUTOCLAM)

autoclam.jpg

● Applications
     · Primarily used for testing the air/water permeability of new surface concrete.
     · Also used for testing the resistance of surface coatings and original/repair materials to the ingress of
       water or water borne salts.  

● Features
     · The autoclam is a portable instrument used to measure the air and water permeabilities and the water
       absorption of concrete and other porous materials.
     · Measurements obtained can provide vital information relating to the ingress of harmful materials such
       as carbon dioxide or chloride ions.
     · These penetrate through the cover layer of concrete to the steel in porous form or in solution.
     · Major corrosion damage can then occur.
