NJ-R72 Rebar corrosion and concrete resistivity tester

简要描述: Application: used to test the degree of steel-bar corrosion by electrochemical method, and to test concrete resistivity by Wenner sensor array (50 mm spacing)

产品介绍

Application: used to test the degree of steel-bar corrosion by electrochemical method, and to test concrete resistivity by Wenner sensor array (50 mm spacing)

 

Standard:

GB 50204-2015 Code for quality acceptance of concrete structure construction

GB/T 50344 -2004 Technical standard for inspection of building structure

JGJ/T 152-2008 Technical specification for test of reinforcing steel bar in concrete

 

Features:

1. Two test modes: The potentiometry and gradient method is used to test steel-bar corrosion which suitable for different working field.

2. Permanent reference electrode: Saturated CuSO4 solution is sealed up completely in reference electrode. Field test keeps clean, simple and pollution-free operations.

3. Automatic measure environmental temperature. Instrument is with a environmental temperature module, it can measure, record and display temperature quickly, no need thermometers.

4. Can save test date. Convenient for data management.

5. Display test result intuitively by icon mode, The icon color is more dark, the steel-bar corrosion is more serious. User can observe the corrosion degree intuitively.

6. USB transmission. Data can be transmitted to computer for future process and analysis.

7. Powerful data process and analysis software, test data can be exported to word or excel for future process and analysis.
