PCE-HT-225A Hardness Test Instrument
PCE-HT-225A is a hardness test instrument or concrete test hammer, also called a concrete rebound hammer or Swiss hammer, used for non-destructive measurements of surface hardness and compression strength. Suitable for use with concrete, rock and building materials, this manufacturer-calibrated manual rebound hammer is economical, practical and easy to use.
The quality of concrete is judged mainly on the basis of compressive strength, since compressive strength is directly responsible for the structural behavior and durability of concrete constructions. The compressive strength is designated by a sequence of letters and numbers. For example, "B 25" is considered normal concrete with a compressive strength of 220 kg / cm² or 3100 psi. There are many intermediate values up to the highest strength class of "B 55." Thus, using this concrete hardness tester, you can quickly, easily and accurately classify concrete strength.
