SOLID Popular Special Concrete Strength Measuring

Brand:Solid

Model: HT-225

Name: Concrete Test Hammer

Origin: Tianjin, China

Explanation

Consistent   withGB/T9138-1988   standards   and

JJG817-93 statutes and JGJ/T23-2001 technical

regulations.HT-225 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.
