Welcome to Porter Instrument, the global leader in analytical, dental, industrial 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, Porter Instrument products are trusted for their precise regulation and measurement of anesthetic gases in operating rooms and dental/medical offices worldwide and for the Silhouette nitrous oxide masks and nitrous oxide scavenger systems.

Porter Instrument supplies advanced Nitrous Oxide Sedation Systems and Emergency Oxygen Systems for progressive dental and medical practices. All of our products are 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.
