SURFACE STRESS METER 

SURFACE STRESS METER FOR TEMPERED GLASS(REF.ASM-100-3)

The Surface Stress Meter is designed for measuring compression stress of tempered glass.It makes the light spread along the surface of glass and then the value of surface stress and depth will be tested through photoelastic principle.Computer equipped will be used to reduce measurement error caused by operator and also be available for data management.In addition,automatic titrator and thickness gauge are in option to achieve efficiency improvement.

FEATURES
■peculiar Measurement Principle-Photoelastic Analysis Refractormeter 
■automated testing reducing errors caused by operators
■computer to save data for quality control
■manual testing available when samples are not in good tempered condition
■LED lamp with 10000 hours serving time
■Master Piece to achieve system self-calibration.
■automated determination of qualified or unqualified according to operators’ setting while continuous testing in progress
■data saved and testing times displayed immediately while continuous testing in progress 
■single and manual measurement in option 
■automated Immersion Drop Function controlled by specific software to reduce Immersion liquid cost
