TEM-R62 Concrete Resistivity Tester

The R62 concrete resistivity tester is also called the potential tester (corrosion analyzer). The corrosion of the steel in the concrete is an electrochemical process. It produces the current to dissociate the metal. The lower the resistivity, the more easy the corrosion current flows through the concrete, the greater the possibility of corrosion, and the resistivity of the concrete can be effectively measured. The corrosion resistance is evaluated and the corrosion degree of existing steel bars is evaluated.

Performance
1. Test mode. Sponge type sensor ensures good electrical contact.
2. Easy operation. Test on the surface of the concrete, without destroying or drilling it.
3. Include a standard test block. To ensure the reliability of the measurement results.
4. Automatic measure environmental temperature. The instrument contains a temperature
measuring module. It can measure, record and display environmental temperature quickly , no need
for thermometers.
5. Can save test date. Convenient for laborer data management.
6. Display test result visually. Display test result directly. The bigger the value, the higher the
resistivity, and the smaller the possibility of corrosion.
7. Real USB transmission. Data can be transmit to computer for future process and analysis.
