Buy an quality Doyen HT-225A concrete test hammer at RT Agencies.

The Doyen HT-225A Schmidt type hammer is put to use in testing the strength of concrete. It assesses the rebound hardness of concrete (elasticity of concrete) and is directly related to the compressive strength of concrete such as that which is obtained in a Lab test using a Concrete Compressive Cube Press.

  • The Doyen HT-225A Test Hammer compares favourably with the original Schmidt Hammer Type N.

The HT-225A Test Hammer also has a measuring range of 20 to 60 MPa compressive strength and can fully stand up in a technical data and quality comparison to the original Proceq Schmidt Hammer.

The rebound value which this portable testing equipment measures is related to the hardness of the concrete being tested. In referring to the conversion chart, the measured rebound value can be used to determine the compressive strength of concrete that is being tested.

The HT-225A hardness tester is widely used in the construction industry.

With this portable test equipment you can determine the quality and strength of concrete and how concrete structures will hold up under strain and pressure.
