DTM-II-H Concrete Dynamic Elastic Modulus Tester
The dynamic elastic modulus analyzer is in line with the standards: ASTM C-215 and C-666, meets the requirement of concrete dynamic elastic modulus test method in SL352-2006 Hydraulic concrete test procedures. Hydraulic concrete test procedures DLT5150-2001, Hydraulic bituminous concrete test procedures DL-T536-2006, can realize full-auto test and analysis by connecting a computer. DTM-II-X (X-categories of the measuring object, H-concrete, J-metallic material, S-plastic product, T-carbon material and so on). It is widely used in light industry, metallurgy, building, bridge, hydroelectric and other fields for modulus of elasticity testing and damping internal friction analysis of concrete, carbon, slabstone, glass, brick, plastic and metallic material.
