Hydraulic Universal Testing Machine
Introduction of Hydraulic Universal Testing Machine
Microcomputer Display-Controlled Hydraulic Universal Testing Machine is designed mainly for tensile, compression, bending, and shearing tests on metallic materials. With the addition of specific attachments, it is also capable of testing wood, cement, concrete, rubber, and related products. The machine’s main unit employs an upper-cylinder structure, where the tensile testing area is located below the main body and the compression/bending area is between the upper cylinder base and lower grip. Adjustments to the tensile space are made by moving the lower grip seat. The force measurement system uses sensors, and the machine operates via an independently developed microcomputer display system, which can show test force, peak values, deformation, and various test curves. It can also print custom test reports or allow users to edit report formats.
