1, function
WDW-S series digital electronic pressure testing machine, mainly for all kinds of glass fiber geotextile, plastic warp knitting geotextile, the geotextile synthetic material, geotechnical grille tensile, bursting, punctures and other mechanical properties test. Precision automatic control and data acquisition system, the data acquisition and control process of the full digital adjustment. In the process of testing, the maximum bearing capacity, strength, elongation deformation, elongation and other technical indexes of the material are detected. After the test is over, the test parameters are automatically calculated by the main controller, and the test results are displayed. The test parameters can be displayed after the test is finished, and the test results can be printed (the printer needs to be customized, the other is paid).
