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.
