Measurement, control, thermographic and infrared instruments
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. The Resipod is the successor of the classic CNS Farnell 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 and even to determination of early compressive strength. This makes it one of the most versatile NDT methods for concrete. 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 early compressive strength; Correlation to water permeability of rock.
