The RH225 Concrete Test Hammer is a professional, non-destructive testing instrument engineered for structural engineers, inspectors, and construction quality-control specialists who demand accuracy, durability, and repeatability. Designed to measure the compressive strength of ordinary concrete in the range of 10–70 N/mm² (1,450–10,153 psi), the RH225 Concrete Test Hammer plays a critical role in modern structural assessment without damaging existing concrete structures.
At the core of its performance is the proven concrete rebound hammer test principle, which evaluates surface hardness and correlates it with in-situ compressive strength. The RH225 is optimized to execute the concrete rebound hammer test with exceptional consistency, even under demanding job-site conditions. From its precision internal mechanism to its rugged outer housing, every design detail supports reliable concrete test hammer use in the field.
Correct execution of the concrete rebound hammer test procedure is essential for obtaining valid and comparable data. The RH225 Concrete Test Hammer features an improved pointer and slider system that ensures smooth movement, easy adjustment, and excellent stability. This design minimizes reading errors and helps operators maintain consistent results during repetitive testing tasks. Whether used for routine inspections or detailed structural diagnostics, the RH225 provides engineers with confidence in every concrete rebound hammer test.
Manufactured in compliance with major international standards—including ASTM C 805 (USA), JGJ/T 23-2011 (China), EN 12504-2, and DIN 1048—the RH225 Concrete Test Hammer is suitable for global projects and professional certification requirements. It is widely applied in building construction, bridge inspection, infrastructure maintenance, and structural evaluation where non-destructive testing is essential.

Key Features of the RH225 Concrete Test Hammer
Accurate Strength Assessment
The RH225 Concrete Test Hammer is designed to perform the concrete rebound hammer test with high reliability, enabling accurate estimation of in-situ compressive strength. Its standardized impact energy and calibrated rebound mechanism ensure consistent correlation between rebound values and concrete strength. This makes it a trusted tool for engineers who rely on repeatable concrete rebound hammer test results for decision-making.
Durable Construction
The outer casing of the RH225 Concrete Test Hammer is manufactured from super-hard 6061 aluminum alloy, offering excellent resistance to impact, wear, and corrosion. Its stretch-formed button design prevents loosening or detachment during prolonged concrete test hammer use. This robust construction ensures long service life, even in harsh construction and inspection environments.
Precision Movement
Internal components of the RH225 Concrete Test Hammer are produced using advanced CNC machining centers, ensuring high dimensional accuracy and smooth mechanical operation. This precision reduces internal friction and improves the repeatability of each concrete rebound hammer test. As a result, operators experience stable rebound behavior and more consistent measurement outcomes.
Fatigue-Resistant Spring
The RH225 Concrete Test Hammer utilizes an imported, high-quality spring integrated into an aluminum alloy assembly. This spring offers excellent fatigue resistance, maintaining stable elastic performance over thousands of impacts. Consistent spring behavior is essential for reliable concrete rebound hammer test results, especially during long-term or high-frequency testing programs.
Components Included
Each RH225 Concrete Test Hammer is supplied as a complete professional kit, including:
- Rebound hammer
- Silicone hand protector with ergonomic hand rest
- Grinding stone
- Maintenance kit
- Pointer slider and buffer spring
- Protective instrument box
This comprehensive package ensures the RH225 is ready for immediate concrete test hammer use and easy long-term maintenance.
