Integrated Digital Schmidt Hammer HT-225D with optional microprinter

 

Introduction

 

HT-225D is is specifically applicable to the on-site quality sampling inspection by Engineering Quality Supervision Institutions and Supervising Units, for the compressive strength test result of the inspected concrete structure can be got immediately; when the Construction Quality Testing Institution carries out on-site test for real construction objects, it can further reflect the fairness, scientificity and accuracy of the test, greatly improving the working efficiency of testing, data processing and inspection report formation.

 

Structure of Concrete Test Hammer


The Concrete Test Hammer is mainly composed of flip system, value-indicating system and shell component.Its structure is shown in Fig.1. The diagram shows the state that the impact hammer has finished impact in the test and the pushbutton has locked the movement,ie.retaining state of resilience value.
