Optical Comparators

Optical Comparators

The optical comparator has been a staple in the manufacturing environment since the 1920s. It’s a tried and true technology because of its familiarity and simplicity. While it is being replaced in some applications by more sophisticated vision measurement equipment, the optical comparator still has its place in the manufacturing environment.

S-T Industries

For more than 70 years, SCHERR-TUMICO measuring products have been produced in Southwestern Minnesota. The tubular frame micrometer was introduced in the early 1940s, the Model 1500 vertical beam optical comparator in the 1950s, and the Model 2500 30″ optical comparator in the 1960s. Since 1983, S-T Industries, Inc. has expanded its product lines to include a full range of precision hand measuring tools, optical comparators, and video inspection systems.
