The 1.5ADP-RPR probe adapters give you the ability to measure the location of a 1.5" SMR nest with a portable CMM measuring system. The adapter is a partial 1.5" diameter ball, precisely machined to hold the center of a spherical probe tip at exactly the same point in space as the center of the 1.5" SMR. This allows you to accurately measure the positions of nests and target mounts designed for 1.5" SMRs.

Cutaway view (above) shows 1.5ADP-RPR probe adapter sphere with tip of portable CMM probe (in red) located at the center of the sphere.

The 1.5ADP-RPR comes in handy if you are required to use multiple measuring systems on one job, cannot obtain line-of-sight with a laser, or only have access to a portable CMM.  The center point of the probe's spherical tip is held precisely 0.75" or 19.05mm above the surface of the part being measured.  To construct the appropriate part number, substitute the diameter of your probe for "A" in the legend shown below.  E.g., to fit a 3mm probe, the part number would be 1.5ADP-RPR-3.
