CORNERSTONE METROLOGY SERVICE, INC.

Cornerstone Metrology Service, Inc. specializes in the calibration, repair, and preventive maintenance of high-precision electronic and industrial equipment critical to defense and federal operations. Their core expertise lies in ensuring metrological traceability and compliance with military and NIST standards through on-site calibration of laboratory instruments, test benches, and precision measurement systems. The company delivers accredited calibration services for sensors, gauges, data acquisition units, and control systems, maintaining strict adherence to ISO/IEC 17025 and MIL-STD-45662 protocols. Their technical proficiency extends to the servicing of non-electronic industrial machinery, demonstrating adaptability across complex test environments where accuracy and uptime are mission-critical. Differentiators include rapid on-site response, documented chain-of-custody for calibrated assets, and experience supporting time-sensitive military exercises requiring uninterrupted equipment readiness. The contractor maintains a consistent and focused relationship with the Department of Defense, delivering mission-critical metrology services across multiple installations. Their work supports readiness initiatives by ensuring the operational integrity of test, measurement, and diagnostic equipment used in weapons systems validation, avionics testing, and field maintenance operations. Engagement patterns suggest recurring, long-term partnerships tied to base-level infrastructure sustainment and exercise support, indicating trusted status within DoD logistics and maintenance chains. Cornerstone operates primarily under NAICS 811210 for electronic and precision equipment repair and maintenance, with secondary activity in 811310 for commercial and industrial machinery servicing. This positions them as a niche provider for defense-grade metrology and equipment lifecycle support, serving sectors where calibration accuracy directly impacts safety, compliance, and mission success. They are not a general maintenance vendor but a specialized metrology services firm focused on high-stakes technical environments. As a Women-Owned Small Business and Woman-Owned Business certified entity headquartered in Van Nuys, California, Cornerstone leverages its small business status to meet federal sourcing goals while delivering technically rigorous, compliant services. Their geographic location enables efficient support across the Western U.S. defense industrial base, with a reputation for reliability in austere and high-demand operational settings.
