Porter Instrument, a Division of Parker Hannifin

Welcome to Porter Instrument, the global leader in dental and medical instrumentation. Since our inception in 1968, Porter has specialized in the development, manufacture and sale of precision instruments for the measurement and control of gases and liquids. Our 54,000 square foot fully-integrated headquarters and manufacturing facility is located in Hatfield, PA, 35 miles northwest of Philadelphia.

Porter Instrument's passion for precision dates back to our founder's invention of a tube-forming machine utilizing a heat/vacuum process, capable of precisely sizing the internal dimensions and configuration of glass tubing within 50 millionths of an inch. This invention led to the first production of interchangeable, glass rotameter tubes.

Today, in the same tradition of precision, Porter Instrument products are trusted for the regulation and measurement of anesthetic gases in operating rooms and dental/medical offices worldwide.

Porter Instrument supplies advanced products for two major components of progressive dental/medical practices: Nitrous Oxide Sedation Systems and Emergency Oxygen Systems. Each is unique, and designed to meet the standards of Best Management Practices.

In short, when the application has no room for error, the world can put its trust in Porter Instrument.
