Moeller Instrument Company, Inc.

Moeller Instrument Company, Inc., a small business subchapter S corporation based in Ivoryton, Connecticut, manufactures and supplies precision measurement and test equipment as a prime contractor to federal defense agencies, with no subcontractor involvement across its federal contract footprint. The company specializes in pressure dial gauges, indicating thermometers, self-reading thermometers, compound pressure gauges, clinometers, and vacuum indicators for military aviation maintenance and logistics operations.

Moeller's customer concentration is extreme and narrow. The Defense Logistics Agency Aviation accounts for 3,379 awards with $42.5 million in combined potential value—representing 94 percent of the company's total federal contract dollars and 98 percent of all awards in the source data. The remaining customer base is negligible: Defense Logistics Agency (general) placed 113 awards ($554 thousand), the Department of the Navy Naval Sea Systems Command issued 18 awards ($28 thousand), DLA Land and Maritime awarded 7 orders ($36 thousand), and the Department of Homeland Security US Coast Guard funded 6 awards ($24 thousand). This concentration reflects Moeller's role as a specialized supplier of precision instrumentation exclusively to DLA Aviation's aviation maintenance enterprise.

Moeller holds two active single-award Indefinite Delivery Contracts with DLA Aviation, both designated as total small business set-asides and extending through February 2030. The primary IDC, awarded February 28, 2025, carries a $1,762,031.46 ceiling for self-reading thermometers (NSN 6685-00-042-3218) with performance in Ivoryton, Connecticut. The secondary IDC, awarded February 24, 2025, provides $250,000 in ceiling value for pressure dial gauges (FSC 4610118575), also through February 2030. These two vehicles anchor Moeller's federal business; three large delivery orders under the thermometer IDC alone total $695,541.26 as of June 2025. The source data also references older IDCs from September 2022 with $250,000 ceilings that appear to have completed. Moeller issues the balance of its federal work as firm fixed-price purchase orders directly against these IDCs.

Activity has declined significantly year over year: 177 awards in 2022 fell to 92 by 2024, with 101 awards in 2025 and only 32 awards recorded through April 14, 2026 in the source snapshot. The source identifies 36 awards with ultimate completion dates within the next twenty-four months, carrying combined potential value of $321 thousand—a modest recompete exposure given the company's reliance on its two primary IDC vehicles. Representative recent purchase orders include a $32,690.88 total small business set-aside for pressure dial gauges (February 17, 2026), a $26,785.92 total small business set-aside for self-indicating thermometers (September 29, 2025), and a $76,589.64 delivery order for self-reading thermometers under the primary IDC (June 9, 2025). The company manufactures all equipment directly from its Ivoryton facility and maintains no identified subcontractors across the federal contract record.

Moeller's primary NAICS category is 333415 (Other Measuring and Controlling Device Manufacturing), accounting for 1,731 awards, with secondary concentration in NAICS 333417 (Automatic Environmental Control Manufacturing), representing 1,261 awards. Primary PSC concentration is 4610 (Pressure, Temperature, and Humidity Measuring and Controlling Instruments)—3,473 awards—with minor exposure in PSC 5835 (Navigational Instruments) covering 86 awards. The company competes in full-and-open procurements on roughly half its purchase orders and under total small business set-aside designations on the remainder, reflecting its consistent small business posture across DLA Aviation's supplier base. Moeller does not hold positions on government-wide acquisition contracts, BPAs, or GSA Schedules; its entire federal footprint routes through DLA Aviation IDCs and purchase orders.
