PCE Instruments PCE-HT-225A Hardness Tester, for Material Hardness Testing, Provides Accurate Readings, Along with a Portable Design and Easy-to-Use Interface

The PCE-HT-225A Hardness Tester for concrete is easy to use and is fundamentally used in the construction industry as well as other industrial sectors (testing for hardness of rolls in commodities). This Hardness Tester in the form of a hammer device for testing concrete is based on the Schmidt principal of measurement. Testing is always done under the same test energy of 2207 J. The kinetic energy of the rebound is given by the device as the measurement of the hardness of concrete, of the pressure upon the surface or as the resistance to pressure (kg/cm² or its conversion to N/mm²). The quality of concrete is useful in understanding the material's resistance to pressure, as an orientating value for testing the load capacity and durability of concrete constructions. Resisitance to pressure is represented as a series of numbers and letters, for example: B 25 indicates that the material is normal concrete with a resistance to a pressure equal to 25 N/mm². Different readings exist up to the highest class of resistance which is indicated as B 55. With our Hardness Tester you will be able to easily and accurately classify concrete.
