Used in conjunction with a suitable electronic balance for specific gravity determination of fresh and hardened concrete and aggregates. A purpose built robust frame designed to support the electronic balance.The lower part of the frame incorporates a moving platform, which carries the water container allowing the test specimens to be weighed in both air and water. The balance is included in the apparatus. Any type of electronic balance fitted with an under-bench weighing facility can be used.

The density of asphalt pavement is directly proportional to the dielectric constant of the measured material.The gtj-2701 USES an innovative, spiral-shaped magnetic field detector to test the dielectric constant in the presence of a magnetic field generated by the sensor plate. The electronic components of the gtj-2701 convert the field signal into a material density reading displayed on the screen.Once the instrument is calibrated, the density can be read at once.

This series of testing machine is loaded by hydraulic pressure, and the manual control technology is used to test the stretching, compression, bending and shearing of metallic and non-metallic materials, showing various curves, forces, deformation, displacement and other closed-loop control methods, which can be switched freely in the test.Automatic recording of stored data. Can meet GB, 1S0, ASTM, DIN, JIS and other standards.

This series of testing machine is loaded by hydraulic pressure, and the electro-hydraulic servo control technology is used to conduct tensile, compression, bending, shear and other tests on metallic and non-metallic materials, showing a variety of curves, forces, deformation, displacement and other closed-loop control methods, which can be switched freely in the test. Automatic recording of stored data.

This series of testing machines is clamped in the form of hydraulic jaws,controlled by a hand-controlled valve to control the testing machine,and a testing machine that displays the test curve by a microcomputer screen display.lt is mainly used to stretch,compress and bend metal and non-metal materials.Tests such as cutting,shearing,etc.,computter screen display load curve,force value,loading speed,displacement,etc.,aytomatically record data,print data results.The host uses four-column double-screw test space architevture and high-strength,high-toughness,and beautiful protection nets for security protection.It is a necessary equipment for research institutes,matallurgy and machinery factories,quality in spection stations,and universities and colleges.
