Perma™ is a laboratory test device that measures the electrical resistance of concrete against the penetration of chloride (RCPT) according to the standard methods such as ASTM C 1202, AASHTO T 277 and ASTM C 1760.
The measurements can be used to estimate the chloride diffusion coefficient of concrete, which enables predicting the service life of concrete structures. Perma™ can also be used for durability-based quality control purposes.
Perma™ is electrically certified for rapid chloride penetrability test in concrete laboratories and its measuring cell sizes are according to the ASTM and AASHTO specifications.
