“This is an instrument that is developed to measure surface stress of chemically tempered glass and thermally tempered glass automatically.”
       Be equipped with a computer(PC) that reduces measurement errors happened by each operator. Besides,complex calculation required to calculate surface stress and depth of layer for chemically tempered glass is quickly solved by PC automatically. Data storing in PC memory directly makes quality control easily.
“Make it possible to measure chemically tempered double ion exchanged glass.”
       Newly released FsmV software make it possible to measure double ion exchanged glass in addition to thermally tempered glass and single ion exchanged glass that were applied with former software.
“Graphic displays of sectional stress distribution.”
       Evaluation of double ion exchanged glass is easily performed because distribution of sectional stress is graphically displayed.
