Rebar Corrosion Detector



  • Measure the surface potential of concrete so as to nondestructively detect the degree of corrosion of steel bars in concrete.
  • The potential value at the corresponding position of each test area is stored and displayed graphically.
  • The corrosion of steel bars in structural concrete reduces the effective cross-sectional area and increases the volume of steel bars, leading to concrete expansion and spalling.
  • Corrosion detection and measuring the degree of corrosion assists in safety assessments of structures and buildings.

•Waterproof, dust proof, shock proof
•Electrode size : Φ 30 mm x 120 mm
•Built-in lithium battery
•Test accuracy :1mV
•Measuring space : 1~100cm
•Data storage
•GB/T19001-2016 / ISO 9001 : 2015 compliant manufacturer
