NEWPORT® offers the industrial and research user a complete line of thermocouple assemblies. NEWPORT’s standard types are listed in this section, which includes a wide selection of component parts, partial assemblies, and complete assemblies ready for installation. Many other styles of components and assemblies are also available. NEWPORT is always glad to quote based on your special needs.

Thermocouple Extension Assemblies
Selection of thermocouple heads is made on the basis of operational requirements, accessibility, and/or the need to avoid direct contact with hot surfaces. Also, it is often required that the extension permit removal of the thermocouple element. For these requirements, NEWPORT offers a complete line of configurations and component parts which can be configured for specific applications. NEWPORT® extensions are made of 1/2" NPT standard weight galvanized steel nipples and unions.
