WDW-S series digital display electronic universal pressure testing machine_Electronic universal testing machine series_详情

1. Brief introduction

WDW-S series digital display electronic pressure testing machine is mainly used to test the mechanical properties of various glass fiber geotextiles, plastic warp-knitted geotextiles, geosynthetics, and geogrids for tensile, bursting, and puncture. The precise automatic control and data acquisition system realizes the fully digital adjustment of the data acquisition and control process. During the test, the technical indicators such as the maximum bearing capacity, strength, elongation deformation and elongation of the material are tested. The above detection parameters are automatically calculated by the main controller according to the test parameter conditions set at the beginning of the test after the test is over, and the corresponding test results are displayed at the same time. After the test, each test parameter can be queried and displayed or printed (the printer needs to be customized , Additional cost), additional accessories can be used for mechanical performance testing of other materials.

Product design, manufacturing and inspection are based on the relevant provisions of the following standards

1) GB/T2611-2007 "General Technical Requirements for Testing Machines"
