LS STARRETT CO

LS Starrett Co. specializes in the precision calibration and metrological maintenance of high-accuracy granite surface plates and related dimensional measurement equipment, serving critical defense and industrial applications. Their core expertise lies in traceable calibration processes compliant with ANSI/ASME B89.3.7 and NIST standards, ensuring surface flatness, parallelism, and planarity meet stringent military and aerospace tolerances. Using interferometry, electronic level sensors, and automated data acquisition systems, they deliver certified calibration services that uphold the integrity of inspection workflows in manufacturing and quality control environments. Their technical differentiation stems from deep familiarity with granite metrology standards, meticulous environmental control during calibration, and the ability to document and certify results to DoD quality assurance requirements without external oversight. The contractor maintains a consistent relationship with the Department of Defense, providing calibrated measurement standards essential for inspection, tooling verification, and production line quality assurance across multiple defense installations. Their work supports ordnance, aerospace, and armored vehicle programs where dimensional accuracy directly impacts system performance and safety. Operating under NAICS 811210, LS Starrett Co. is positioned as a niche provider in precision equipment maintenance, focusing exclusively on metrology services rather than general electronics repair. This vertical specialization enables them to serve defense contractors and government labs requiring certified, repeatable calibration of reference standards. As a small business structured as a 2L entity based in Waite Park, Minnesota, LS Starrett Co. operates without federal certifications but leverages technical proficiency and geographic proximity to key defense logistics hubs to maintain a reliable presence in the federal metrology services market. Their operational model emphasizes precision, documentation integrity, and compliance with federal calibration protocols.
