The Stanone STMH1 Type N Rebound Concrete Test Hammer is the quickest, simplest and least expensive method for (NDT) non destructive evaluation of compressive strength of concrete and other masonry materials. Also referred to as a mechanical concrete rebound test hammer, swiss hammer & sclerometer, It is most ideally suited for assessment of material uniformity over large areas of structure to delineate the zones or areas of poor quality or deteriorated concrete present in the structures.
It provides a measure of relative material surface hardness and is used extensively for the testing of concrete and rock. The hammer consists of a spring loaded plunger which when released, strikes the surface. During the rebound stroke, the mass moves a pointer providing a reference value on the scale called the rebound number. This number, when converted based on correlation table, gives the compression resistance value in respect of the impact angle.
The STMH1 Mechanical rebound test hammer for concrete testing, is possibly the highest quality instrument available for its purpose, and is engineered based on an all aluminum body with a 4 layer protective coating for ensuring against oxidization ; Inside parts are High tensile steel springs , Stainless steel centre rod, “EN” mass with hard chrome plating , Zinc rails - every component of the instrument is designed and made to exacting standards to ensure that the instrument provides the highest level of repeatability during measurements and durability.
