For more than 70 years, SCHERR-TUMICO measuring products have been produced in Southwestern Minnesota. The tubular frame micrometer was introduced in the early 1940's, the Model 1500 vertical beam optical comparator in the 1950's and the Model 2500 30" optical comparator in the 1960's. Since 1983, S-T Industries, Inc. has expanded the product lines to include a full range of precision hand measuring tools, optical comparators and video inspection systems.
