Tell-Tales are precision gauges that consist of two plates which overlap for part of their length. The bottom plate is calibrated in millimetres and the top plate is transparent and marked with a red hairline cursor in the form of across.

It is essential that products used for monitoring changes in crack width are quality precision instruments.
Great reliance is placed on the result of the monitoring and the user may be liable if inappropriate remedial work is recommended based on the results of imitation products of inconsistent quality.
