Product Description

HT-225 Concrete Test Hammers are used to determine the surface hardness of concrete and is one of the most widely used instruments in the field of non destructive testing (NDT) of concrete compressive strength. It is the quickest, simplest, and least expensive method to obtain an estimate of the quality and strength of the concrete. 

This type test hammer is used to test the concrete compressive strength of construction and bridge...
