Mortar Test Hammer - Mechanical Type, Schmidt Test Hammer
Product Code: CN502
Application
This device is a mortar rebound test apparatus, a spring rebound hammer, and it measures the restoration force of the sudden elastic deformation caused by the impact rod striking a mortar-like surface, thereby directing the hammer indicator to rebound and displaying the rebound distance.
As one of the relevant indices for evaluating the compressive strength of mortar, the compressive strength and label of the mortar are estimated. It is an instrument used for the non-destructive examination of the compressive strength of wall mortar in sintered common bricks of general buildings in industrial and civil constructions.
