**Surface Stress Meter for Tempered Glass (Ref. ASM-100-3)**
The Surface Stress Meter is a specialized instrument designed to measure the compressive stress on the surface of tempered glass. It utilizes light that spreads across the glass surface, and by applying the photoelastic principle, it measures both the surface stress value and the depth of the stress layer. A computer is integrated into the system to minimize measurement errors and manage data efficiently. The device supports both automated and manual testing, making it adaptable for different sample conditions. Optional accessories such as an automatic titrator and thickness gauge are available to enhance operational efficiency.
**FEATURES**
1. Unique Measurement Principle – Photoelastic Analysis Refractometer
2. Automated Testing Reduces Human Error
3. Computer System for Data Storage and Quality Control
4. Manual Testing Option for Samples That Are Not Perfectly Tempered
5. Long-Lasting LED Light with 10,000 Hours of Operation
6. Masterpiece for System Self-Calibration
7. Automatic Judgment of Pass/Fail Based on Operator Settings During Continuous Testing
8. Real-Time Data Saving and Display of Testing Counts During Operation
9. Optional Single or Manual Measurement Mode
10. Automated Immersion Drop Function Controlled via Specific Software to Minimize Immersion Liquid Consumption
