For corrosion assessment

• The LCN700 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.
• Complies with the proposed AASHTO standard for a surface resistivity test for estimating hardened concrete permeability.
• 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:

• Simple to use
• Fully integrated surface resistivity instrument
• Highest resolution available for a surface resistivity instrument
• Hold, save and delete function, with onboard memory
• USB connection and dedicated PC software
• Designed to float (waterproof)

Applications:

• Surface resistivity test on standard cylinders 4″ x 8″, 100mm x 200mm or 6″ x 12″, 150mm x 300mm) with a maximum aggregate size of 1.5″, 38mm. Fixed probe spacing (1.5″, 38mm)
• Correction factor for probe spacing
• Surface resistivity mapping on site for: estimation of likelihood of corrosion, corrosion rate & implementation of cathodic protection systems

Resipod Surface Resistivity (SR) Method:

• In 2011 the American Association of State Highway and Transportation Officials (AASHTO) became the first standards body to define permeability classes based on resistivity measurements (TP95-11 Standard Method of Test for Surface Resistivity Indication of Concrete’s Ability to Resist Chloride Ion Penetration).

Since that time this test has established itself as a simple, economical alternative to the ASTM C 1202 Rapid Chloride Permeability test with several clear advantages:

• Much faster to perform
• No sample preparation necessary
• Test can be repeated at different ages e.g. 28 days, 56 days
• The same cylinder can be used for compressive strength testing

LCN700 Resipod with 1.5” (38mm) probe spacing is fully compliant with the above-mentioned standard.

Software:

• All measurements saved on the Resipod may be downloaded for analysis with the software included with all models.
• User defined correction parameters may also be defined in the software and uploaded to Resipod.
