PCE-HT-225A Concrete Hardness Tester

The PCE-HT-225A is an indispensable, economical, and portable tool for civil engineering and the construction industry. It operates by applying a specified elastic force to impact the concrete surface, subsequently measuring the redistributed kinetic energy as a rebound value. Because structural concrete quality is primarily judged by compressive strength, this manual test hammer allows engineers to quickly and accurately classify the strength of concrete slabs, beams, and columns, differentiating normal concrete (e.g., “B 25”) up to high-strength classes like “B 55”.

Durable, 100% Mechanical Operation Engineered to withstand rugged construction environments, the PCE-HT-225A stands out by utilizing a strictly mechanical rebound test method—it contains zero digital components. This makes it highly dependable on job sites where batteries or delicate electronics might fail. Interpreting the results is seamless; users simply read the rebound value on the scale and refer to the conversion tables printed directly on the back of the instrument to find the equivalent Kg/cm², psi, or MPa value, taking into account the impact angle (e.g., 90° or 45°).

Versatility Across Industries While it is primarily built to test concrete, rock, and building materials, the Schmidt-method principle makes the PCE-HT-225A surprisingly versatile. Beyond structural engineering, it is also utilized in manufacturing sectors to test the winding hardness of large rolls of commodities. To ensure test accuracy on rough building sites, the complete kit includes a grindstone to properly prepare the test surface before taking impact measurements.
