Which code does this activity belong in?
Code 334515 covers establishments that manufacture instruments specifically designed to measure and test electricity and electrical signals, such as circuit testers, voltmeters, and multimeters. The boundary separates this code from 334513, which covers instruments that measure industrial process variables like temperature and pressure rather than electrical characteristics. Code 334515 also differs from 334516, which manufactures analytical laboratory instruments for chemical composition analysis, not electrical testing.
