HT-75A brick rebound tester

HT-7 brick rebound tester is used for non-destructive testing of the compressive strength of sintered porous bricks or sintered ordinary bricks

Functional Features

High toughness alloy steel springs with good damping and fatigue resistance when purchased;

Precision suitable for CNC precision machining of refined movements, confirming stable rebound values

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

The precision ground spherical zero adjustment screw is matched with a high-strength hook, making rebound firing smoother and wear-resistant (based on actual reports), and less likely to bounce off

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

Customized protective sleeve handle for more comfortable rebound operation

Data processing software that supports raw record input, facilitating the production of inspection reports
