The S-T Industries Story

For more than 60 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.


Every SCHERR-TUMICO optical comparator and video inspection system receives a thorough inspection and certification before it leaves our factory. This assures you there will be no surprises at your facility. These products are not mass produced on an assembly line, but hand crafted and tested through each step of the process to guarantee that you will receive a reliable and proven instrument.


SCHERR-TUMICO optical comparators and video inspection systems are designed to give you the best value for your investment. We have a unit for any job or budget. Whether you need a small, economical machine or a large, CNC measuring system, you’ll find we have a product to fit your needs. We also build special systems and tools for unique applications.
