About the company
Sheldon Instruments Inc., a small-business manufacturer of embedded computing hardware and infrared scanning instrumentation, operates as a prime contractor exclusively, holding a single-award Blanket Purchase Agreement with the U.S. Department of Agriculture Forest Service for airframe software upgrade services. The company is a for-profit Subchapter S Corporation headquartered in La Mesa, California, competing entirely under Total Small Business set-asides across its federal footprint. Sheldon Instruments' work centers on embedded Linux-based systems modernization, airframe instrumentation software engineering, and infrared scanning platform upgrades — capabilities reflected across primary NAICS codes spanning communications equipment manufacturing, electrical measurement instrumentation, and computer peripheral equipment manufacturing.
Customer concentration is extreme: the Department of Agriculture Forest Service Washington Office Acquisitions accounts for 90% of awards and $50.5 million of the $50.6 million combined potential value across the entire federal portfolio, effectively a single-customer vendor. Air Force work represents three awards but carries no dollar-value characterization in the source. The Forest Service Fire and Aviation Management National Interagency Fire Center rounds out the active customer set with one award valued at $141 thousand. The vendor's only named vehicle is the $50 million single-award BPA with USDA Forest Service (Blanket Purchase Agreement 12760423A0003), running through August 31, 2028, against which two task orders carrying $256 thousand combined potential value have been issued to date. Recent work includes a September 2026 $64,950 Total Small Business purchase order for the Phoenix NexGen infrared scanning system modernization — the final phase of migrating the airborne platform from Windows to Linux-based embedded single-board computer hardware, including fabrication of Sheldon's SI-DRA-SBC compact computer module, software modernization, and twelve months of maintenance — and a September 2024 $123,789 BPA call for Forest Service instrumentation software upgrade services. The vendor has obligated only $1.4 million of its $50.6 million potential value (3%), indicating a heavily backlogged or unevenly executed vehicle. One award carries completion within the next twenty-four months, exposing $65 thousand to recompete.
