Explanation

Consistent withGB/T9138-1988 standards and JJG817-93 statutes and JGJ/T23-2001 technical regulations.HT-225B Concrete Test Hammer generally applied to building components, bridges and all kinds of concrete components (panels, beams, columns, bridges) strength.

Features

1) Center guide rod using imported materials, high precision

, wear-resistant;

2) Use of super-hard aluminum shell to avoid on-site work

injury apparatus, to extend the service life;

3) Pointer slider with external spring ring structure, both

convenient for the friction adjustment, and ensures that the

pointer shaft and pointer slider friction uniform, to ensure

the accuracy of the instrument.

  Peer-products is relatively high accuracy, quality and

cheap, long service life.
