Rebar Corrosion Tester NL 4049 X / 001

Concrete Corrosion Testing

The Rebar Corrosion Tester is specialized apparatus, it is designed according to the electrochemical testing method (natural potential method) of “construction testing technical standard”. The steel corrosion on the structure of concrete reduces the effective section area of steel and increases in volume, which leads to the expansion of concrete, spalling, reinforcement of steel and concrete, and the reduction of bearing capacity, directly affect the safety and durability of concrete structure.

*High detection accuracy (accuracy of corrosion voltage is ±0.1 mv)
*The test result are displayed in hierarchical graphics
*Two working modes of single and double electrode
