The 3490-010 Stainless Steel Ball Base “Contour” w/Magnet features:
• Ball prism base “outline” for straight and curved edges
• For use with 1.5″ (38,1 mm) diameter prism balls
• Integrated permanent magnet
• Height-offset HO: 25 mm, stainless steel, base-Ø 40 mm
• The tip of the quadrant lies exactly in the center of the base
• Positional accuracy of the quadrant tip to the center axis base/prism: ± 0.02mm
• Magnet holding force: 4.0/2.4kg
The base is placed onto the object and held with the tip (= base center) against the contour edge. After aligning the ball prism with the tachymeter, the measurement can take place. Due to the permanent magnet built into the base, the ball prism sticks reliably to the base. With the “Contour” base, both straight and curved edges can be measured.
