High Quality Resiliometer Concrete Rebound Hammer Tester Concrete Rebound Test Schmidt Hammer HT225 (Engineering Plastics Case) 

item

Introduction:

The HT225 Concrete Test Hammer is designed specifically for the non-destructive testing of concrete structures.This method has considerable advantages over conventional methods of assessing the compressive strength of concrete in that large areas can be tested in a very short time at a very low cost.

The HT225 is comparable with the Schmidt Hammer,Type N,this method of testing is covered by EN 12 504-2,ASTM C 805,DIN 1048 and BS1881 part 202.These standards refer to assessment of the rebound hardness of concrete which is directly related to the compressive strengths of the material being tested.

 

Scope of application:

Is suitable for the detection of general building components, bridges and various components (Quan plate, beam, column, bridge) compressive strength.

 

Main features:

1) the center guide rod adopts imported material, which has high precision and wear resistance.

2) the shell uses the super hard aluminum to avoid the field operation damage instrument and prolong the service life.

3) the pointer slide block adopts external spring ring structure, which not only facilitates the adjustment of friction force, but also ensures the uniform friction between the pointer shaft and the pointer slide block, so as to ensure the accuracy of the instrument. Relative products have high precision, high quality, low price, and long service life.
