Optical glass thickness gauge

With the crack depth card, you can measure cracks in different materials quickly and precisely. The card has an opposing scale on both sides, making it easier to read crack depths in different directions.

This transparent crack width map is produced by laser exposure instead of printing, which enables extremely precise visualisation of fine crack widths. It is particularly suitable for users who require greater accuracy than is possible with the printing process.

Stable crack width chart made of plastic in graduations from 0.05 mm to 1.2 mm in 0.05 steps, as well as 1.3 / 1.4 / 1.6 / 1.8 / 2.0 / 2.5 / 3.0 and 3.5 mm.
On the reverse side, coloured fields indicate the temperature in 1° C steps (from 8° to 32° C.).
