Key Features and OperationPurpose: It quickly estimates the compressive strength of concrete in columns, beams, bridges, and slabs.Working Principle: The device shoots an internal spring-loaded mass against the concrete surface. The distance the mass bounces back—known as the rebound value (R-value)—is read on the built-in linear scale graph.Conversion: Higher rebound values indicate a harder surface and higher concrete strength. This number is cross-referenced using the printed chart on the barrel to find the estimated strength in Megapascals (MPa) or PSI.
