A crack monitor, sometimes known as Tell Tail is used to confirm long term changes in the width of established cracks. This monitor is designed to measure rotation, transverse and longitudinal movement.

This inexpensive crack measuring device enables accurate determination of whether cracks exceed the maximum allowable crack width. This loupe also comes in a self-illuminating model, powered by two c-cell batteries the measuring magnifier may be used in poorly lit areas where natural light is dim or non-existent.

Crack Width Meter cards are useful for spot checks of crack width during construction.

The crack width camera combines smart crack detection and measurement with a close focus camera to immediately measure and document crack widths in a construction project.
