Cracks, take the right measures

The purpose of the G2 type gauge is to measure and record the changes in the gap of an expansion joint, the gap between the edges of a gap and/or, more generally, the change in distance between 2 elements.
This G2 Saugnac Gauge is based on the same two concepts:
A record of the maximum/minimum variation in the gap is traced by a N°7B lead onto a white graduated scale.
The G2 gauge avoids visits for monitoring changes, especially helpful when the gauges are difficult to reach.
As a general rule, adhesive tabs are sufficient. If the structure does not have a very satisfactory surface, spread a thin layer of glue or attach by mechanical means: three 2.5 mm holes are provided for this purpose.
On damaged surfaces with distortion in many directions, we advise fixing the arm of the gauge with a ball joint ( please enquire)..
To measure and record the change in a gap or joint in an internal angle, we suggest using an angle bar. We can supply self-adhesive aluminium angle bars on request. (30 X 20 X 3 mm)
One wing of the angle bar is attached to one part of the structure. The other wing has the arm of the gauge attached to it, the latter being attached to the other part of the structure under observation.
