The HT-225A Concrete Rebound Tester is a professional non-destructive testing (NDT) device developed and manufactured by Zhejiang Yiyu Instrument Equipment Co., Ltd. This product is primarily used to test the compressive strength of concrete structures such as buildings, bridges, and tunnels.
Core Design and Technical Highlights
High-Quality Materials: Utilizes imported Korean SWP piano steel springs, offering excellent rebound resistance and greater fatigue resistance than ordinary springs.
Durability Design: Equipped with NBR sealing dust rings, ensuring internal cleanliness of the movement and effectively extending equipment maintenance intervals.
Precision Manufacturing Process: The movement is precision-manufactured using CNC machining centers and other precision machine tools, ensuring the accuracy and stability of the rebound value.
Operating Comfort: The outer layer features a soft and wear-resistant rubber sleeve, providing greater comfort for operators during extended use.
Detail Optimization:
- Smooth Excitation: Equipped with a precision-ground spherical zero-adjustment screw, ensuring a smoother rebound excitation process.
- Stable Pointer: The improved pointer design not only facilitates easy friction adjustment but also ensures more stable operation.
- High-Strength Components: High-precision aluminum alloy flanges are durable and resistant to damage; high-strength hooks are wear-resistant and less prone to slack.
Sturdy Structure: The main unit adopts an integrated shell design, ensuring that the guide keys and brackets will never be damaged or fall off. The buttons are manufactured using a stretching process, making them less prone to falling off.

Frequently Asked Questions (FAQ)
Q1: What engineering tests is the HT-225A mainly used for?
A: It is mainly used for non-destructive on-site testing of the compressive strength of various concrete structures (such as buildings, bridges, and tunnels).
Q2: How is the measurement accuracy of this rebound hammer guaranteed?
A: By using a CNC-machined movement and imported piano steel springs, combined with strict steel anvil calibration before leaving the factory (controlled between 80-81), the accuracy and stability of the rebound value are ensured.
Q3: Is this instrument easily damaged in harsh environments?
A: Not easily. Its NBR sealing ring effectively prevents dust, and the integrated shell and high-precision aluminum alloy flange design greatly enhance the durability of the structure, enabling it to adapt to high-intensity construction site working environments.
Q4: Can the pointer friction be adjusted?
A: Yes. This instrument adopts an improved pointer design, making friction adjustment simple and more stable during use.
