BABINET TYPED SURFACE STRESS METER BTP

Surface stress of Heat-strengthened and annealed glass is measured by

Since it is babinet typed equipment , sensibility is high and a personal equation of measuring is small.

This is compact and everyone can use and carry to everywhere.

This can measure a curveture glass.

ASTM C1279 details the test methods for measuring surface and edge stresses in heat-treated and

annealed glass. This BTP used for these procedures.
