Mortar Test Hammer 

CT-140 applies to inspect compressive strength of mortar in

masonry for industrial and civil buildings in general sintered

common brick masonry.

Our test hammer can meet the international standards:ASTM

C 805, BS 1881:202, NF P18-417, DIN 1048 and UNI 9189.

Features

1) Center oriented rod using imported materials, high precision,

wear-resistant;

2) As per shell use superhard Al alloy material, therefore it avoid

to damage instrument in-site woke, and to extend the instrument's life;

3) Pointer slider with external spring ring structure, not only it is

convenient for the friction adjustment, but also it ensures that

the friction force for pointer shaft and slider is uniform, and to

ensure the accuracy of the instrument.
