HT-225 hammer impact / smith hammer test / concrete hardness tester for compressive strength concrete

 

Introduction

HT-225 is applied to test the compressive strength of building concrete components, bridge and so on. HT-225 submit to standard of GB/T9138-1988 and JJG817-93 and JGJ/T23-2011 and ASTM C 805.

 

Features

1.Center rod is made from imported material.

2. High Aluminum case extend use life.

3. High accuracy and durable resistance.

4. Pointer slider is outside structure, its friction can be balance well and easy to be adjusted so that we can           make sure that the instrument is accurate.
