Problems solved by technology

However, because the ground simulator represented by oxyacetylene is limited by many harsh test environments such as high temperature and pressure, the traditional contact online test device cannot meet the test requirements. For the online test of surface temperature and strain of special environmental materials, it is necessary to use Non-contact online measuring device
