DRK8093 Dial Stress Meter

The WYL-3 dial stress meter is an instrument used to measure the birefringence of transparent objects due to internal stress. It has both quantitative and qualitative functions, simple and convenient operation, very suitable for industrial applications.

The source of this stress (birefringence) is caused by uneven cooling or external mechanical effects. It directly affects the quality of optical glass, glass products, and transparent plastic products. Therefore, stress control is an extremely important part of the production process of optical glass, glass products, and transparent plastic products. This stress meter can qualitatively or quantitatively identify the quality of products (tested parts) by observing stress. It is widely used in optical glass, glass products, and transparent plastic products industries for rapid and large-scale inspections, which solves the problem that mathematics cannot actually be passed. Complex issues.
