Official definition
This U.S. industry comprises establishments primarily engaged in manufacturing instruments and instrumentation systems for laboratory analysis of the chemical or physical composition or concentration of samples of solid, fluid, gaseous, or composite material.
When to use a different code
Census classifies these close-sounding activities somewhere else. Businesses mainly engaged in:
- Manufacturing instruments for monitoring and analyzing continuous samples from medical patients are classified in U.S. Industry 334510, Electromedical and Electrotherapeutic Apparatus Manufacturing.
- Manufacturing instruments and related devices that measure, display, or control (i.e., monitor or analyze) industrial process variables are classified in U.S. Industry 334513, Instruments and Related Products Manufacturing for Measuring, Displaying, and Controlling Industrial Process Variables.
