SXSZ-R72S

Product usage： 

The SZ-R72S concrete resistivity and rebar corrosion tester combines the functions of the R61S rebar corrosion tester and the R62S concrete resistivity tester. It can simultaneously assess the corrosion level of rebar within concrete using both the resistivity method and the half-cell potential method. This multi-functional device allows for cross-validation of results from both methods to determine if corrosion has occurred within the concrete.

Performance features:
1. Two testing methods for measuring the corrosion level of rebar within concrete: the half-cell potential method and the resistivity method, suitable for different testing environments.
2. The corrosion test uses a permanent reference electrode with saturated copper sulfate solution sealed inside, ensuring a simple, clean, and non-polluting operation process.
3. New generation product design: compact and exquisite, with a rubberized casing, waterproof and dustproof silicone buttons, and comfortable handling.
4. Features a color LCD screen with an elegant interface and simple operation.
5. Removable battery: lithium battery can be removed for charging or charged directly via a power bank, facilitating on-site use.
6. Latest Type-C interface: the main unit's charging/data transfer port uses a Type-C interface.
7. Automatic environmental temperature detection during corrosion testing: the instrument includes an automatic temperature measurement module, eliminating the need for a separate thermometer, making the process convenient and quick.
8. Simple resistivity testing method: employs the traditional four-electrode method (Winner four-electrode method), with a sponge plug sensor ensuring good electrical contact, and no need to damage or drill into the concrete, allowing testing directly on its surface.
