About Arroyo Instruments, LLC
Arroyo Instruments, LLC, a San Luis Obispo, California–based for-profit manufacturer of electrical and electronic instruments, operates as both a prime contractor (76% of recent awards) and subcontractor on federal research and development procurements, supplying specialized test equipment, controllers, sources, and emulators to civilian and defense agencies. The company operates in full-and-open competition with no SBA set-aside designations across its recent federal footprint.
Arroyo's capability portfolio centers on the design and manufacture of electrical measurement and testing instruments, temperature and current controllers, combo sources, optical components, and specialized test equipment for space flight and ground systems. Representative prime work includes a $66,215 purchase order from the National Institute of Standards and Technology in June 2024 for 17 combo sources, a $47,610 procurement from NASA's Shared Services Center in May 2023 for current and temperature controllers and cables, and multiple small R&D task orders from the Department of the Navy's Office of Naval Research for specialized electrical and electronic components. On the subcontractor side, Arroyo supplies test equipment and emulator systems to Honeywell Federal Manufacturing & Technologies under the National Security Campus management and operations contract (Department of Energy National Nuclear Security Administration), with three sub-awards valued in the low thousands between February and September 2025, and provides electrical and electronic engineering support to Columbus Technologies and Services for space flight hardware development under a NASA award issued in April 2026.
Customer concentration skews toward research-intensive civilian agencies. The Department of Commerce National Institute of Standards and Technology leads by potential value ($419 thousand across 3 awards), followed by NASA Shared Services Center and NASA Goddard Space Center (3 awards, $29 thousand combined), the Department of the Air Force Materiel Command (2 awards, $23 thousand), and the Department of the Navy Office of Naval Research (4 awards, $17 thousand). These five entities account for 88% of recent awards. The vendor's award footprint is sparse and sporadic — one award in 2023, one in 2024, three in 2025, and one in 2026 — with combined potential value of $548 thousand across 17 total awards spanning back to 2008. Obligated dollars exceed potential value at $1.1 million, indicating settled invoicing on completed work. Arroyo's technical categories center on electrical and electronic component manufacturing (NAICS 334513 and 334519) and laboratory equipment supply (PSC codes for electrical testing instruments and laboratory equipment), with secondary exposure to optical components and semiconductor-related manufacturing.
