Point Finder is a high precision 3D touch sensor (probe) which is enable to do any kind of measurements, such as reference position, inside / outside diameter, centering, angle, groove width, and height.
All model has nonmagnetic stylus, and its repeatability is assured of ±0.5μm with the standard length stylus.
There are 5 models as PTN, PTC, WP, SPi, WPi.

Repeatedly even with a 80mm stylus length accuracy ± 1μm guarantee (Patent No. 5133884)
