**Surface Stress Meter for Tempered Glass (Ref. ASM-100-3)**
The Surface Stress Meter is specifically designed to measure the compressive stress on tempered glass surfaces. It uses a light beam that spreads across the surface of the glass, and through the photoelastic principle, it calculates both the surface stress value and the depth of the stress layer. A computer is integrated into the system to minimize measurement errors and support data management. This device can be operated manually or automatically, offering flexibility depending on the condition of the sample. Optional accessories such as an automatic titrator and thickness gauge are available to enhance efficiency and accuracy.
