Langry Rebound Hammer / Schmidt Rebound Hammer, 70 MPa

Rebound Hammer for Concrete Strength Testing The Rebound Hammer is a reliable non-destructive testing (NDT) instrument used to determine the surface hardness and estimate the compressive strength of concrete structures. It is designed for rapid, simple, and on-site testing of concrete quality in both new and existing structures such as buildings, bridges, and pavements. This precision-engineered hammer works on the principle of measuring the rebound of a spring-driven mass impacting the concrete surface. The rebound value is directly related to the surface hardness of the material, which can be correlated to compressive strength using standard calibration curves. Key Features Durable Construction: Made from high-quality materials ensuring consistent performance and long service life. Accurate Readings: Provides reliable and repeatable results for compressive strength estimation of concrete (10–70 N/mm²). Easy to Use: Lightweight and ergonomically designed for single-handed operation at any angle. Calibration Facility: Supplied with a steel anvil for periodic calibration checks to maintain accuracy. Standard Compliant: Conforms to IS 13311 (Part 2): 1992 / ASTM C805 / EN 12504-2 for rebound hammer testing. Applications: Ideal for field testing of concrete structures, quality control, comparative testing, and detecting areas of poor compaction or deterioration.
