This kit provides all the Geo crack monitor devices for a professional to monitor a structure.
Rather than order separate gauges, this single kit provides the complete range of Geo crack monitoring devices at a reduced price.
Geo Tell Tale Standard
Standard Tell-Tale crack monitoring gauge provides monitoring for both horizontal and vertical movement across a crack on a flat surface.
Features a precision silk screened grid, detailing both positive and negative graduations.
Geo Corner Tell Tale
The Geo Corner Tell Tale crack monitoring gauge is a simple instrument for monitoring the movement of cracks in corners. An additional 90 degree acrylic plate allowing for secure fixing to the second surface.
A precision silk screened grid, detailing both positive and negative graduations. The fine red crosshair allows for accurate estimation.
Geo Crack Width Gauge
Prior to monitoring changes in the width of cracks it is necessary to measure the crack width. This is called the present condition or 'snapshot' survey.
Measuring scales: cm, 1/600m, 1/1200m and width gauge graduated from 0.04mm to 1.40mm.
Geo Displacement Tell Tale
A simple Tell-Tale that monitors displacement and horizontal movement where there is a 'step' across a crack due to displacement or 'out of plane' movement. A two piece instrument, one part place either side of the crack. The red line should be central to the grid on the second piece placed on the opposite side of the crack.
Movement of the crack will 'draw' one of the sides, allowing for movement reading either horizontally or vertically.
Crack recording sheets are supplied with each unit to allow accurate recording of movement over a period of time.
