This simple crack width ruler has been designed to provide inspectors with a low cost alternative to a graduated microscope for determining the width of a crack in concrete or other building materials.

Similar in size to a standard credit card, this transparent concrete ruler is marked with a range of graded lines, each with a specified width.

To use, position the gauge over the crack and identify which line is a similar width to the crack. Read off the width value.

This is a very simple, graduated x50 microscope with internal illumination.

This allows the user to quickly determine width by counting the number of graduated reticules on the scaled lens and calculating the value.
