Resipod Concrete Surface Resistivity Meter

Surface resistivity measurement provides extremely useful information about the state of a concrete structure. Not only has it been proven to be directly linked to the likelihood of corrosion and the corrosion rate, recent studies have shown that there is a direct correlation between resistivity and chloride diffusion rate.




The versatility of the method can be seen in these example applications:
• Estimation of the likelihood of corrosion
• Indication of corrosion rate
• Correlation to chloride permeability
• On site assessment of curing efficiency
• Determination of zonal requirements for cathodic protection systems
• Identification of wet and dry areas in a concrete structure
• Indication of variations in the water/cement ratios within a concrete structure
• Identification of areas within a structure most susceptible to chloride penetration
• Correlation to water permeability of the rock

Resipod is a fully integrated 4-point Wenner probe, designed to measure the electrical resistivity of concrete in a completely non-destructive test. It is the most accurate instrument available, extremely fast and stable and packaged in a robust, waterproof housing designed to operate in a demanding site environment
