Simple and Reliable
Illuminates Stress Areas
Instantly Determines Heat Strengthened Glass
The CRL Heat Strengthened Glass Detector Kit provides a simple and reliable
means of determining whether glass panes are heat treated by illuminating the
stress zones created by the heat strengthening process. By shining the specially
filtered, battery operated light source on the reverse side of the glass, and
observing through the special glasses included with the kit, stress zones become
rainbows of color. Annealed glass will remain clear when viewed using this
technique. Kit comes complete with flashlight light source, filtered glasses,
two "D" cell batteries, and a padded carrying case along with detailed
instructions. You will want extra kits for your Service Department Personnel and
your Quality Control Specialists.
