The G3 gauge is designed to measure the evolution of a vertical misalignment (rocking floor slabs) or horizontal misalignment or, more generally, the evolution of out-of-plane movement, perpendicular to an X,Y reference plane.
It consists of a 50 mm cubic body, an arm integral with the body, and a 70 mm stainless steel rod that fits into the arm and rests against the structure to be monitored. The engaged length of the rod is adjusted according to the size of the misalignment to be measured.
Monitoring the evolution of a horizontal misalignment (structures lying in a horizontal plane): floor slab failure or ceiling sagging (A = structure whose movement is to be measured, B = fixed reference structure, d = misalignment)
Monitoring the evolution of a vertical misalignment (structures lying in a vertical plane): pillar out of alignment or sliding structure (A = structure whose movement is to be measured, B = fixed reference structure, d = misalignment)
The measurement is taken using a vernier reading to 0.1 mm, corresponding to 0.2 mm of movement.

C: Plane XY
D: Misalignment
(1) double-sided adhesive pad 50 x 50 mm
(2) stainless steel rod Ø 4 mm, length 70 mm
Its cube shape allows it to be used in any position: along a skirting board, or in a vertical or horizontal internal corner, by choosing one of its 5 faces to fix the gauge (see below for installation examples).
Two fixing methods are possible:
Fixing is quick and easy with the double-sided adhesive pads supplied. The adhesive pad is applied to one of the 5 available faces of the cube, so the fixing can be adapted to the location and the measurement to be taken. Two pads are supplied, so that the gauge can be reused or a bonding error corrected.
For the bond to be effective, the surface must be smooth and clean. If necessary, particularly if the surface is not perfectly flat and has rough spots, the bond can be reinforced with a fast-curing epoxy glue in a twin syringe. In this case, the epoxy glue can also be applied directly to the gauge without the double-sided adhesive pad.
Where the surface is very uneven, or crumbles with a risk of the gauge coming loose, we recommend using an intermediate plate. This plate is mechanically fixed to the surface with impact anchors (supplied with the plate), and the gauge is bonded to the plate, which then becomes the mounting surface.
A: 2 x 4/40 screws, B: Intermediate plate, C: Adhesive pad, D: Misalignment gauge
The rod length is adjusted according to the size of the misalignment: an offset of up to approximately 50 mm is possible; beyond that, a special assembly is required. Please contact us if needed.
We offer protection with a thermoformed plastic cover or an IP65 aluminium cover.
A semi-flexible, transparent cover measuring 27 x 13 x 9 cm protects the gauge from the weather, dust and vandalism. The cover is fixed to the surface with a self-adhesive strip and impact anchors.
For “high protection”, we offer aluminium enclosures measuring 175 x 80 x 57 mm (depth).
The reading is taken using the vernier principle, to 0.1 mm. Note the letter of the side read (A or B) so that measurements are always compared on the same side over time.
The millimetre graduation located to the left of the ꓕ gives the measurement as a whole number of mm. In the example, the reading is therefore: 12 mm.
Find the vernier line that coincides with a line on the measuring scale.
This vernier line gives the tenth of a millimetre. In the example, the reading is therefore: 0.4 mm
Due to the design of the gauge, for geometric reasons, the change in misalignment is equal to twice the difference between the 2 measurements.
∆h in mm = (M2 – M1) x 2
Example:
We offer an add-on recording kit to be mounted on the G3 gauge. This kit graphically records the maximum and minimum deformation of the structure.

The Saugnac web app, completely free with no limitations, is available on PC or smartphone at https://saugnac.app. Each G3 gauge has a unique QR code and ID to link the measurements to the gauge. The application allows you to:
