TK-R62 concrete resistivity tester is also called potential tester. Corrosion of steel bars in concrete is an electrochemical process. The lower the resistivity, the easier the corrosion current will flow through the concrete, and the greater the possibility of corrosion. Therefore, measuring the resistivity of concrete can effectively evaluate its anti-corrosion ability and evaluate the corrosion degree of existing steel bars.

• Test method. Sponge plug sensor ensures good electrical contact;
• Simple to use. The concrete can be tested on its surface without breaking or drilling it;
• Contains standard blocks. There is a standard test block to ensure the reliability of the measurement results
• Test date can be set for the instrument. Data saving test date, convenient data management.
• Visual display of test results. Direct display results are used. The higher the value, the higher the resistivity and the lower the possibility of corrosion.
