Ohmcorr Resistivity Meter - Corrosion Currents in Concrete

RM-8000 OHMCORR

Resistivity Meter to Assess Corrosion Currents in Concrete

Features
  • Assesses damaging corrosion currents in concrete.
  • Economic and easy to use.
  • Direct digital readout of resistivity. Measuring from two small holes avoids the problems and errors of surface measurements.
  • Used in conjunction with CorMap system to produce resistively plots.
Technical Information

The electrical conductivity of concrete is an electrolytic process that takes place by the movements of ions in the cement matrix. This ionic movement will take place when contaminants such as chloride ions or carbon dioxide are introduced into the cement mortar matrix.

A highly permeable concrete will have a high conductivity and low electrical resistance. Because resistively is proportional to current flow, the measurement of the electric resistance of concrete surface should be avoided.

The resistively meter, OHMCORR, has two probes spaced 5cm(1.97 inches) apart which Are placed in two holes drilled to a depth of 8mm(3/8 inch) and filled with conductive gel. The concrete resistively is displayed on an LCD When the control switch is activated.

The following table correlates arrange of Values vs. the possible rate of corrosion of the Reinforcement bars.
