S-18 strain gauge can be qualitative polarizing transparent glass or plastic for the internal stress testing, adjusted the glass products annealing or plastic products injection molding, blow molding, etc. Polarized S-18 field strain gauge adequate, holding the sample, through the polarized light in the vertical or horizontal orientation of the sample to be tested. Strain gauge glass polarized S-18 Reference Data: field of view: 260mm x 260mm working space: 260mm Overall Size: 445x280x280mm Additional Accessories: sodium monochromatic S-18a-color full-wave CD: S-18b S-18 strain gauge through a polarizing observation of patterns and colors, to measure the annealing before / after the stress of glass, and then annealing the device to measure the work. Eligibility criteria by the manufacturer to develop. The detection of plastic abrasive is more complex. Despite the stress test pattern is generated, but irregular. Glass products will be similar, and this phenomenon is called stress stretch.
