16VS Vertical Beam Optical Comparator

With it’s dynamic head optical system this is the first of its kind manufactured in the USA. This new system allows a much greater stage capacity of up to 250 pounds, with optional measurement range up to 16" x 8", making it the largest capacity benchtop measuring instrument in the world.

This ultra precision optical co

This rugged snap gage features a precision box-way range adjustment channel to protect the anvil shafts and maximize frame clearance.

J2 Horizontal Jaw Gage

The Dorsey E1 comparator stand is specially designed for use in production and shop areas. The comparator stand has a large base and 3" throat clearance to give the user maximum flexibility for measuring various size pieces.

Ultra Large Diameter Gages

This "ultra large diameter gage and setting master series" was developed to measure part sizes beyond those of the Dorsey Metrology traditional large diameter gage family. The ultra large series measures large parts in the range from 60", 1500mm to 240", 6000mm. These instruments are designed to be accurate, rigid, stable, lightweight and durable.

Roto Round Concentricity Fixtures

The roto round is an adjustable fixture used to check concentricities, run-out, and or TIR of one or more surfaces to a basic diameter. Three precision bearings set the primary datum plane and support the weight of the part while 2 roller bearings mounted on the angled base define the circular datum. Indicators then contact the part as it is being rotated to determine various parameters.
