SIC 3825
INSTRUMENTS FOR MEASURING AND TESTING OF ELECTRICITY AND ELECTRICAL SIGNALS

This industry is made up of companies that manufacture a multitude of analytical devices. Examples of industry output include voltmeters, ammeters, wattmeters, watt-hour meters, semiconductor test equipment, and circuit testers. Establishments that produce monitoring and testing equipment for navigational, radar, and sonar systems are described in SIC 3812: Search, Detection, Navigation, Guidance, Aeronautical, and Nautical Systems and Instruments.

Industry Snapshot

Shipments of instruments to measure electricity increased in value every year from 1991 to 1997. After falling slightly from 1997 to 1998, values continued their upward climb, reaching $16.1 billion in 2000. This industry did not suffer as badly as many did in the recession of the early 1990s. Many establishments came into operation in the 1980s, and employment for this industry was highest in 1984. In the late 1980s, U.S. companies were shipping more than $7 billion worth of goods per year, employing around 90,000 workers, and exporting equipment valued at about $2 billion annually. While shipment values more than doubled from 1987 to 2000, the number of people employed (62,136) was about 35 percent less than 1984's record high of 95,800. The average hourly wage in 2000 was $18.95.

Growth in the mid-1990s was due to demand for automatic test equipment (ATE), a devalued U.S. dollar, and shipments of high-tech devices to telecommunications industries. Despite increased foreign competition, the United States widened its trade surplus to $2.6 billion in 1996 and poised itself for steady global expansion into the 2000s.

Organization and Structure

The electrical testing and measuring (T&M) instruments industry encompasses eight major product groups. ATE, the largest industry segment, includes T&M instruments for semiconductors, circuit boards, and computer disk drives. Communications test equipment, the second-ranked product group, includes T&M devices for landline, wireless, and fiber-optic communications gear.

Other major industry categories include signal generators, electrical integrating instruments, multimeters, oscilloscopes, and spectrum analyzers. Each of these product groups is comprised of many different devices. In addition, more than half of industry revenues are garnered from a wide range of miscellaneous T&M instruments, such as tube testers, impedance measurers, frequency meters, battery testers, stroboscopes, tachometers, reflectometers, ammeters, and...
