Industry Snapshot
Key metrics for the other measuring and controlling device manufacturing industry.
Industry Definition & Overview
Other Measuring and Controlling Device Manufacturing (NAICS 334519) encompasses establishments primarily engaged in manufacturing measuring and controlling devices not classified under more specific instrument codes for environmental controls, industrial process variables, electricity, analytical laboratories, irradiation, or electromedical apparatus. Products include physical properties testing equipment, nuclear radiation detection and monitoring instruments, aircraft engine instruments (except flight), surveying instruments, drafting instruments, and timing devices. The U.S. Census Bureau[5] positions this as a residual classification capturing diverse measurement devices.
Roughly 811 active businesses employ approximately 34,200 workers in this industry per Census data[6]. Product diversity spans mechanical hardness testers and material strength testing machines to sophisticated radiation dosimeters and nuclear monitoring stations. Surveying instruments including total stations, theodolites, and GPS receivers for land surveying serve the construction and geospatial industries. Aircraft engine instruments such as tachometers, exhaust gas temperature gauges, and torque meters serve aerospace OEMs and maintenance operations.
Manufacturing processes vary widely given the product diversity, from precision optical assembly for surveying equipment to ruggedized electronic packaging for radiation detectors. Many firms serve multiple end markets simultaneously, leveraging core measurement expertise across industrial, aerospace, nuclear, and construction applications. Government customers include the Nuclear Regulatory Commission, Department of Energy nuclear facilities, and Department of Defense testing programs that procure radiation monitoring and physical property measurement equipment through specialized procurement channels.

Key Insight: The SBA[8] sets the size standard for NAICS 334519 at 600 employees. Firms below this threshold qualify for small business set-aside contracts and SBA-backed lending programs. Federal procurement spans radiation monitoring equipment for nuclear facilities, physical testing instruments for military materials laboratories, and surveying equipment for Army Corps of Engineers projects. The SBA's contracting programs[9] support manufacturers pursuing Department of Energy and Department of Defense instrumentation contracts. Eligible businesses can access SBA 7(a) loans[10] for working capital, equipment, and acquisition financing, while 504 loans[11] support major fixed-asset purchases including real estate and heavy machinery.

Frequently Asked Questions
Common questions about this industry.
What types of businesses are classified under NAICS 334519?
This residual code covers manufacturers of measuring and controlling devices not fitting specific instrument categories. Physical property testers, radiation detectors, aircraft engine instruments, surveying instruments, timing devices, and drafting tools all classify here per the Census Bureau[5] classification.
How is the other measuring device manufacturing industry structured?
Roughly 811 businesses employ approximately 34,200 workers per Census data[6]. The product diversity means firms range from large manufacturers of materials testing machines to small specialty producers of radiation dosimeters and surveying accessories, with limited direct competition across product categories.
What is the SBA size standard for NAICS 334519?
The SBA[8] sets the threshold at 600 employees. Businesses with fewer than 600 average employees qualify as small for federal contracting preferences and SBA-backed financing programs including 7(a) and 504 loans.
What NAICS codes are related to other measuring device manufacturing?
Related codes include 334512 (Environmental Controls), 334513 (Industrial Process Instruments), 334515 (Electrical Test Instruments), 334516 (Analytical Laboratory Instruments), 334511 (Navigation Systems), and 334514 (Fluid Meters). Each covers specific measurement types pulled from this broader residual classification.
What industries purchase other measuring and controlling devices?
Nuclear power operators, construction firms, surveying companies, aerospace maintenance providers, and materials science laboratories represent the primary customer base. Government agencies including the Nuclear Regulatory Commission and Department of Energy procure radiation monitoring equipment and physical testing instruments through federal procurement programs.
What activities are included in NAICS 334519?
