   DTM-II-H Dynamic Elastic Modulus Damping Internal Friction Analyzer

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-catagories 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.
