Proceq Original Swiss Schmidt concrete test hammers are used for the non-destructive measurement of concrete/mortar compressive strength and the control of the uniform concrete quality (in-situ concrete and prefabricated structures) as well as for detecting weak spots. The compressive strength (fc) is established by measuring the hardness (rebound value R) of the concrete surface in conjunction with the conversion curves.
Proceq Original Swiss 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). Versions with paper chart recorders (LR and NR) can automatically register the rebound values on a paper chart roll.
Combined measuring with the ultrasonic instrument TICO increases the accuracy.
Model N, NR, ND, L, LR, LD are suited for measuring the compressive strength of concrete of 1,450 to 10,152 PSI (10 to 70 N/mm2).
