Ohmcorr Test System
Resistivity Meter for Concrete

Resistivity meter to assess corrosion currents in concrete.

• Confirm readings made with either Cor Map System

Features & Benefits

• 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 resistivity plots.

The James OhmCorr™, when used in conjunction with the James CorMap™ System provides an economic and sound means of diagnoses of corrosion in reinforced concrete.

Specifications
