This Surface Stress Meter measures surface compressive stress of chemically tempered glass and the depth of stress layer according to photoelastic technology by letting light spread along the glass surface.

This instrument is equipped with a PC, which can reduce measurement errors caused by operators . Moreover, it is more convenient for the management of measuring data. Thickness Gauge is optional to improve the measurement efficiency.

It has been widely used in the quality control for phone glass panel , LCD panel and other chemically tempered glass panel .

Measuring object
Chemically tempered glass
