RH225 Concrete Test Hammer is an essential, non-destructive testing instrument engineered for structural engineering professionals. It is meticulously designed to measure the compressive strength of ordinary concrete within a range of 10 to 70 N/mm² (1,450 to 10,153 psi) with exceptional reliability. Understanding the principles of the concrete rebound hammer test is key to structural assessment, and the RH225 is built to execute this test with unparalleled accuracy. Every aspect of its construction is optimized for the rigorous demands of a concrete test hammer use on job sites worldwide. The correct concrete rebound hammer test procedure is vital for data integrity, and our improved pointer design ensures easy adjustment and superior stability for consistent readings. Whether you are conducting a standard concrete test hammer use for quality control or a comprehensive concrete rebound hammer test for structural analysis, the RH225 delivers confidence. It is manufactured to meet and exceed the toughest international standards, including ASTM C 805 (USA), JGJ/T 23-2011 (China), and various European norms (EN 12504-2, DIN 1048).
