The test is performed through applying a voltage difference between the ends of a concrete specimen, one end is the negative and is immersed in a sodium chloride solution, the other is the positive and is in a sodium hydroxide solution. Testing procedure to ASTM While keeping 60 VDC difference between the specimen ends, current (Ampere) transmitted through the specimen is accu­rately measured over time calcu­lating the total charge (Coulomb). starting from the measured total charge, the instrument provides qualitative indications of the chloride ion penetrability level (from High to Negligible).

The test fixture are designed suitable for both cubes and cylindrical concrete specimen. Equipped with  corrosion-resistant electrodes, the tester can be used for long time. 

The automatic acquisition and control system makes the test results accurate.
