60 - 90Mpa Concrete Testing Equipments 5.5J HT-550 High Strength Test Hammer

HT-550 High Strength Test Hammer To Test The Bridge Component Compressive Strength

HT-550 High Strength Test Hammer

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. The instrument is used for quality Inspection Company, site testing or sampling and laboratory center.

Standard:

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

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

Parameters:

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
