产品介绍

Application:

It is used to test the compressive strength of building concrete components, bridge and so on. It is designed specifically for the non-destructive testing of hardened concrete structures. This hammer is suitable for testing strength of tall building structure, bridge and concrete component etc.

Standard:

ASTM C805/C805M-2008 Standard Test Method for Rebound Number of Hardened Concrete

BS 1881 Testing concrete Part 202 Recommendations for surface hardness testing by rebound hammer

BS EN 12504-2:2001 Testing concrete in structures-Part 2: Non-destructive testing – Determination of rebound number

GB/T 9138-1988 Concrete test hammer

JJG 817-93 Concrete test hammer

JGJ/T23-2011 Technical specification for inspecting of concrete compressive strength by rebound method

Features:

1. Pointer slider is outside ring structure, easy to adjust friction, and to assure equal friction between pointer slider and axis.

2. Shell uses super hard aluminums, protect hammer from damage on site work and prolong use life.

3. Center rod uses imported material, high precision and wear proof
