Durometer for Concrete (10 to 60 MPa)
PCE-HT-225A Durometer
Economical, practical and easy-to-use
PCE-HT-225A is a durometer 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.
For psi concrete measurement, download the chart to convert rebound value to psi. Optional test anvil to verify accuracy listed under accessories.
Applications
With the merits of simple structure, easy correction, maintenance and repair, and portability, the Concrete Test Hammer is widely used in civil engineering and construction industry for testing the strength of concrete. Compared to other nondestructive testers, the Concrete Test Hammer is an economical and practical nondestructive testing instrument.
HT-225A is a medium Concrete Test Hammer, its kinetic energy of impact is 2.207J(0.225kgfm). It is extensively used for testing the strength of various concrete members (slab, beam, column) of normal building strength and bridge.
