The 3D precision measuring disk is the superior development of the 3D measuring disk. The disk can easily be screwed or stuck on concrete, stonework and wood. However, the advantage of the 3D precision measuring disk is the wrought countersink; manual centering is not necessary, as the countersink ensures a highly precise placement to ensure excellent results when laser scanning. The raised ridges of the disk will fit the magnet base of a reference spheres or a mini prism, allowing them to be centered easily and precisely.

Product characteristics:

  • external diameter: 50 mm (1.97 in)
  • total height: 7 mm (0.28 in)
  • diameter of centering: 40 mm (1.57 in)
  • depth of centering: 1,5 mm (0.06 in)
  • center hole: 8 mm (0.31 in) diameter with countersink; to be used with M8 countersunk bolt and M8 expansion plug for concrete and stonework
  • 4 concentric holes: 5 mm (0.19 in) diameter with countersink
  • mounting surface allows for the use of a liquid adhesive
  • material: steel, electro-galvanized

Designated use:

  • optimally suitable for highly accurate repeated measurements, such as monitoring measurements and target-actual comparisons
  • attach the reference sphere's magnet base easily and center it immediately
  • for registration or identification of reference spheres and for determination of coordinates by total station

Field of application:

  • permanent marking for reference spheres on walls, concrete, wood and all other surfaces
  • helpful for scanning old walls, ruins or supporting walls on which other permanent marking can hardly be realized
  • alternative marking to the 3D measuring point sticker, for surfaces which don't allow attaching a sticker


  • suitable for 40 mm (1.57 in) magnet base of all reference spheres and mini prisms

Product Contents:

  • 3D precision measuring point disk


  • For the registration, at least 3 reference spheres are required for each laser scanner position. For repositioning the scanner, in some cases it is necessary to position the spheres at another place. Due to the marking on the measuring point disks, a precise centering will always be possible.
