Quick Details
Specifications
this device automatically detects the image luminance, thereby finding the darkest point precisely. By inputting sample photoelastic constant and thickness in advance, the stress value will be calculated by the computer. In addition, Sensitive Color method is used to clearly define the direction of stress.
