Perma™ Enhanced Vacuum Desiccator Assembly

Perma is a laboratory device for measuring the electrical resistance of concrete against the penetration of chloride (RCPT). This data is used to estimate the chloride diffusion coefficient of concrete for predicting service life, durability-based design, and durability-based quality control, of concrete structures. Perma is electrically certified for rapid chloride penetrability tests in concrete laboratories. This device is the only RCPT device that has a CSA electrical safety certification mark for use in concrete laboratories.
