    Concrete multifunctional non-destructive tester

    Device name
    Concrete multi-functional nondestructive tester

    Unilateral propagation

    When the concrete wall thickness is unknown, the P wave can be measured on the same surface to estimate the strength index of the concrete; the virtual multi-channel technology can fully utilize the function of the device to further improve the test accuracy.

    Double-sided transmission

    It is used when there are two test faces (preferably parallel); the energy is strong, and it is also applicable to the larger-sized components (testing 100 meters long) to test the defects, thickness and material of the concrete structure.

    Shock echo method

    When the test object is thin and the excitation signal and the reflected signal are not well separated, the time of the first reflection (ie, the period) can be calculated by the spectrum analysis method, and the thickness of the object can be measured according to the wave speed.


    Test principle and method

    Surface wave method

    According to the attenuation characteristic of one type of surface wave (Rayleigh wave), the deeper the crack, the greater the energy attenuation;

    It is affected by contact with crack faces, steel bars and moisture;

    Not only can the crack depth be detected, but also the crack repair effect can be evaluated;

    Suitable for testing structures with large test surfaces and deep cracks (>10cm)

    The company's original technology is recommended for the Japanese Society of Civil Engineers.


    Test objects: various concrete structures such as bridges, piers, tunnel linings, dams, houses, etc.

    Test content: concrete material: elastic modulus, compressive strength, etc.

    Structure size: thickness

    Surface defects: crack depth, void (peeling), surface degradation

    Internal defects: internal voids, loose, broken

    Test items


    The main components of the instrument are imported from abroad. Based on the shock elastic wave theory, it is compatible with many kinds of technologies at home and abroad and the technology independently developed by the company. The testing accuracy is high. The technology of crack depth detection has been listed as the recommended method of Japan Civil Society.

    product description



    Sichuan Shengtuo Testing Technology Co., Ltd. provides concrete multi-function non-destructive testing instrument. The equipment can be used for concrete material testing, concrete structure testing, concrete strength testing, and concrete internal defect testing.





    IE Analysis Method Based on FFT/MEM

    Special Sensor Support with High Damping and Rigidity

    The test scope is large and the content is rich


    Stable and delicate CT imaging technology

    Distance measurement by water-free coupling cross-hole method

    Rich application schemes


    Results and technical characteristics

    Crack depth test method (surface wave method): it is less affected by steel and crack surface contact;

    Elastic modulus test method: the effect of steel bars can be corrected, and the test accuracy is comparable to the static load test;

    Improved Impact-Echo Method (IEEV): Based on the classical spectrum analysis method FFT, it introduces higher resolution analysis methods and adds intelligent analysis methods, and has two modes of “standard” and “enhanced”.
