The TIME TC600 Rebar Corrosion Detector assesses corrosion of reinforcement in concrete structures using the half-cell potential method. A reference electrode is passed over the concrete surface and the potential voltage difference is recorded, giving a non-destructive indication of how actively the embedded rebar is corroding.

Corrosion of reinforcement is a leading cause of deterioration in concrete bridges, buildings and marine structures, and much of it happens out of sight before any spalling appears. Field potential mapping lets engineers find areas where corrosion is already underway, prioritise repairs and target further investigation, rather than waiting for visible damage.

The TIME TC600 Rebar Corrosion Detector reads potentials across a range of plus or minus 1000mv with a resolution of 1mv, using permanent copper/copper sulphate reference electrodes. The spacing between test points is adjustable from 1 to 100cm, so surveys can be set to the grid resolution a job requires. Readings are held in mass storage and can be stored, viewed, deleted and transferred to a PC over RS232 and USB, then processed as numbers or as grey-scale or full-colour graphics. The main unit of the TIME TC600 Rebar Corrosion Detector weighs 880g and runs on six AA (LR6) batteries from minus 10 to 40 degrees Celsius, with a separate probe of 100g.

Used in corrosion assessment, structural inspection and concrete durability work, the TIME TC600 Rebar Corrosion Detector is supplied by BAMR, South Africa's authorised distributor.
