Applications

This integrated digital rebound hammer is widely applicable to various scenarios, including:

• Construction companies for on-site quality inspection of concrete structures
• Supervision companies for supervision and sampling testing during construction
• Quality supervision departments for on-site random inspection of construction projects
• Testing centers for professional concrete compressive strength testing

It can automatically evaluate test results on-site without manual calculation, greatly improving testing efficiency and accuracy, and is an essential tool for ensuring the quality of concrete projects.

Core Features

1. Independently developed in accordance with internationally accepted technical regulations for rebound testing of concrete compressive strength, with complete independent intellectual property rights.
2. Domestically pioneering integrated structural design, organically integrating the rebound hammer host and sensor into one body without any connecting wires, ensuring easy portability and low failure rate.
3. Taking the lead in adopting a true-color LCD screen with a resolution of 176×220 and a full Chinese operation interface, making it easy to learn and operate.
4. Unique voice prompt function for rebound values, allowing inspectors to know the rebound values in real time without looking at the screen, effectively improving work efficiency.
5. Adopting a non-contact metal reflective grating sensor, which completely avoids mechanical wear, poor contact and other defects easily occurring in traditional potentiometer or other contact sampling methods. It has the advantages of high precision and long service life, and retains the mechanical pointer scale to double ensure testing reliability.
6. Can be connected to an infrared transmission portable printer externally, enabling quick generation of standardized test reports on-site for convenient immediate filing and verification.
7. Large-capacity data storage capability, which can store information of up to 300 standard components, and each standard component can have up to 99 test areas, fully meeting the needs of various actual testing work.
8. The instrument has built-in internationally accepted standard strength curves, and also supports adding regional-specific or industry-specific curves. Users can switch at any time, and it can store up to 20 strength curves to adapt to different testing scenarios.
9. Parameters of components and test areas can be directly entered on-site, and the instrument automatically completes the calculation of component test results without manual intervention, reducing calculation errors.
10. Equipped with an abnormal value automatic elimination function, users can independently set the upper and lower limits of rebound values. Abnormal situations will be warned by both screen display and voice prompt to ensure the validity of test data.
11. Equipped with a USB communication interface, designed in a virtual U disk mode. No need to install any drivers, you can quickly export test data or update special strength curves, making data transmission convenient and efficient.
12. Built-in real-time clock and calendar function, which can automatically and accurately record the test date and time of each component, facilitating the traceability and management of test data.
13. Adopting advanced low-power consumption power management technology, supporting screen backlight adjustment and voice volume control, with automatic sleep and automatic shutdown functions, greatly extending the single use time of the instrument.
