Master Gauge Co

Master Gauge Co, a Chicago-based non-profit organization and small business joint venture, supplies pressure dial gauges and precision measurement instruments to the Defense Logistics Agency as a prime contractor, competing in full-and-open federal procurement with no set-aside designations.

The vendor operates exclusively as a prime contractor — 100% of its recent federal work — with zero subcontract activity. Master Gauge's capability footprint is narrow and specialized: pressure dial gauges dominate the portfolio (25 awards under PSC code for pressure, temperature, and humidity measuring and controlling instruments), with secondary work in observation windows and related precision measurement components. Recent representative work includes a $3,324.50 purchase order from DLA Aviation for a pressure dial gauge awarded November 26, 2025, a $3,685.15 order for a dial gauge awarded March 27, 2025, and a $2,627.37 order from DLA Troop Support Construction and Equipment for observation windows awarded February 12, 2025. All awards are firm fixed-price purchase orders with performance periods spanning weeks to months and ceiling values under $4,000.

Customer concentration is extreme and static. The Defense Logistics Agency Aviation represents 93% of the vendor's award count (25 awards, $73 thousand of the $78 thousand combined potential value), with DLA Troop Support Construction and Equipment accounting for the remaining 7% (2 awards, $5 thousand). The two customer rankings are identical — no divergence between volume and dollars. Master Gauge has no parent contract vehicle participation; all work flows through spot purchase orders.

Activity has been episodic. The vendor received three awards in 2020, two in 2021, five in 2023, four in 2024, and eight in 2025 (as of the source date). Combined potential value across all 27 awards is $78 thousand, with 100% of that amount obligated. No recompete cliff is present; the most recent award was issued December 29, 2025, with an ultimate completion date of March 4, 2026. The vendor has worked with only two federal agencies across its entire recent award footprint, both within the Defense Logistics Agency. The narrow scope, small transaction sizes, and pure commodity nature of the work (pressure gauges) position Master Gauge as a specialized supplier of low-volume, low-dollar precision measurement components for military aircraft maintenance and logistics operations.
