NAICS 334513: Instruments and Related Products Manufacturing for Measuring, Displaying, and Controlling Industrial Process Variables
This U.S. industry comprises establishments primarily engaged in manufacturing instruments and related devices for measuring, displaying, indicating, recording, transmitting, and controlling industrial process variables. These instruments measure, display, or control (monitor, analyze, and so forth) industrial process variables, such as temperature, humidity, pressure, vacuum, combustion, flow, level, viscosity, density, acidity, concentration, and rotation.

NAICS 334513 — Instruments and Related Products Manufacturing for Measuring, Displaying, and Controlling Industrial Process Variables encompasses the design, development, and production of precision instrumentation used to monitor, display, and regulate critical industrial process variables such as temperature, pressure, flow, level, humidity, and chemical composition. These devices include transmitters, controllers, analyzers, data loggers, and process control panels, often deployed in harsh environments requiring high reliability, calibration accuracy, and compliance with federal standards like NIST traceability and MIL-STD specifications.

NAICS 334513 — Instruments and Related Products Manufacturing for Measuring, Displaying, and Controlling Industrial Process Variables encompasses the design, development, and production of precision instrumentation used to monitor, display, and regulate critical industrial process variables such as temperature, pressure, flow, level, humidity, and chemical composition. These devices include transmitters, controllers, analyzers, data loggers, and process control panels, often deployed in harsh environments requiring high reliability, calibration accuracy, and compliance with federal standards like NIST traceability and MIL-STD specifications. In government contracting, this sector supports mission-critical operations across energy, environmental monitoring, life sciences, defense systems, and infrastructure maintenance, serving as the sensory and control backbone for automated industrial and laboratory systems. Top contractors in this space include QUIXLE LLC, QRC, LLC, LINDE GAS & EQUIPMENT INC., BHPE LLC, TMG THE MOORE GROUP INC, and TIMEKEEPING SYSTEMS, INC., representing a mix of small businesses and specialized mid-sized firms with deep expertise in industrial automation, sensor integration, and process control systems. Many hold small business set-asides or 8(a) certifications, reflecting a competitive landscape where niche technical capabilities and regulatory compliance outweigh scale. Primary federal buyers include the Department of the Interior, Department of Defense, Department of Veterans Affairs, Department of Commerce, and Department of Health and Human Services. These agencies procure instrumentation for environmental sampling, hazardous material handling, laboratory automation, facility monitoring, and medical gas delivery systems, driven by mandates for operational safety, regulatory adherence, and infrastructure modernization. The market offers strong opportunity density for contractors with certified manufacturing capabilities, ISO 9001 compliance, and experience in ruggedized instrumentation for federal use. Demand is increasingly tied to digital transformation initiatives, including IoT-enabled process monitoring and predictive maintenance systems, creating openings for firms that can integrate legacy hardware with modern data platforms while meeting stringent federal quality and security requirements.
Small Business Size Standard
The SBA threshold that decides who can bid NAICS 334513 work as a small business.
The SBA cap for this NAICS (13 CFR 121.201). A business at or under it can self-certify as small for work in this code, which is what makes it eligible for a small-business set-aside. The cap is set per NAICS, so the same company can be small in one code and not in another.
13 CFR 121.201, effective January 1, 2026. The SBA revises the table roughly once a year.

Bidder counts reported on past federal awards in this NAICS (USAspending). An open opportunity has no bidders yet, so this is the historical norm for similar work, not a fact about this solicitation. Not all awards report bidder counts, and fewer bidders often means incumbent-held work rather than an easier win. Federal reporting of bidder counts fell from ~96% of awards (FY2016) to ~30% (FY2018 onward); the chart shows shares of reported awards, and washed-out stretches mark years with fewer than 30 of them.
