Proceq Schmidt Concrete Hardness Tester - Ashtead Technology

The compressive strength (fc) is established by measuring the hardness (rebound value R) of the concrete surface and with the conversion curves. ORIGINAL SCHMIDT® Concrete test hammers with various impact energies can be used depending on the form and sizes of the concrete structures (lower impact energy for thin and/or weak components).
