Concrete Rebound Test Hammer HT-550High Strength

Mechanical model

1. Application areas:

The compressive strength of concrete used for structural engineering high-rise building components, bridges, and truss components (plates, beams, columns, bridges) is usually applicable to concrete structures or components with a strength of 50-90MPa.

2. Functional features:

Imported high toughness alloy steel springs have good elasticity and are more resistant to fatigue;

High precision CNC precision machining refined movement ensures more stable rebound value;

The pointer axis is smooth, with uniform friction and high measurement stability;

Precision ground spherical zero adjustment screw matched with high-strength hook, with smoother rebound firing, wear-resistant and less prone to bounce;

Adopting high-strength hard aluminum body shell, it is lightweight and resistant to pressure and drop;

Customized protective sleeve handle for more comfortable rebound operation;
