Resipod Fully Integrated 4-point Wenner Probe-Image

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.

Features

  • Fully integrated surface resistivity instrument
  • Highest resolution available for a surface resistivity instrument
  • Available with 1.5" (compliant with the AASHTO standard) or 50 mm probe spacing
  • Current flow indication and poor contact indication
  • Hold, save and delete function, with onboard memory
  • USB connection and dedicated PC software
  • Designed to float (waterproof)
  • Allows replacement of standard tips with accessories

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

Standardization

Resipod complies with the proposed AASHTO standard for a surface resistivity test for estimating hardened concrete permeability.

Warranties

  • Standard 2-year limited warranty on electronic parts
  • Optional extended warranty periods up to 3 additional years

Resipod Link Software

The Windows based software ResipodLink, developed by Proceq, allows the user to view and manipulate the data on a connected PC. It also allows a variable contact spacing to be set.
