Feature

●The center guide rod adopts imported materials with high precision and wear resistance;
●The shell is made of super-hard aluminum to avoid damage to the instrument during the field operation and prolong the service life;
●The pointer slider adopts an external coil structure, which not only facilitates the adjustment of the friction force, but also ensures the uniform friction between the pointer shaft and the pointer slider, and ensures the accuracy of the instrument
●The rebound hammer determines the average rebound value Rm on the steel anvil: 80±2
●Compared with peer products, it has high precision, high quality and low price, and long service life.


Description

Resiliometer Concrete Rebound Hammer Tester Concrete Rebound Test Schmidt Hammer HT-225

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

Feature:
