Corrosion of reinforcing steel is encountered in variety of reinforced concrete structures.
Corrosion ultimately results in a reduction in the cross section of the reinforcement and spalling of the concrete.  In well-cured concrete, the steel reinforcing bars are protected by the Alkaline composition of the surrounding concrete. As time passes, the Alkaline protection can be eroded either by carbonation or by chlorides.  Once the Alkaline protection is removed, in the presence of oxygen and moisture, the steel is liable to corrode.
Consequently, it is important to detect corrosion at an early stage of its development.
Furthemore, when repairing a reinforced concrete structure, it is important to locate and repair all areas of corroding reinforcement. Half-Cell potential technique is an established and reliable method of measuring and monitoring the condition of reinforcing steel in concrete.
Half-Cell 200 Concrete Rebar Corrosion Tester is used to locate corroding reinforcement without disrupting the concrete cover to the reinforcing steel.  Half-Cell 200 is supplied with  copper sulphate electrode, carrying pouch, 30 meter length extension cable, aluminium bag and instruction manual.
