Product Description

Schmidt Hammer Type N 
This hardness meter 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 resistance to pressure, as an orientating value for testing the load capacity and durability of concrete constructions. Resitance 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 meter you will be able to easily and accurately classify concrete. The hardness meter comes calibrated from the manufacturer but an ISO calibration certificate can be ordered seperately at extra cost.
