Portable Resistivity Meter helps determine corrosion rate.

Press Release Summary:



Consisting of fully integrated 4-point Wenner probe, Resipod measures electrical resistivity of concrete in non-destructive test. During operation, current is applied to 2 outer probes and potential difference is measured between 2 inner probes. Current is carried by ions in pore liquid, and calculated resistivity depends on spacing of probes. Packaged in waterproof housing, Resipod operates in demanding site environments.

RESIPOD - Portable 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 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.

Operating on the principle of the Wenner probe, the Resipod is designed to measure the electrical resistivity of concrete or rock. A current is applied to the two outer probes and the potential difference is measured between the two inner probes. The current is carried by ions in the pore liquid. The calculated resistivity depends on the spacing of the probes.

Resistivity ñ = 2ðaV/l [kWcm]
