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 immediay while continuous testing in progress 
single and manual measurement in option 
automated Immersion Drop Function controlled by specific software to reduce Immersion liquid cost
