Trace oxygen sensors and analyzers for industrial welding gase
The use of inert gases plays an important role in modern welding processes. The welding will be performed in an inert gas protected atmosphere. Monitoring oxygen is essential to produce high yield and improve the weld quality as excess oxygen will be detrimental to the weld seam.
Various welding applications require different inert gases. These gases will be prepared by specialized gas producers that deliver them to the end-user as bottled gases. It is essential for the purity of the inert gas mix that the bottling process is monitored carefully with an oxygen analyzer.

| Application/Service | Measurement | Gas Stream | Analyzer Options |
| Protecting welds from atmospheric (oxygen) contamination by purging the area immediately around the weld with inert gases is essential to enhancing quality and reducing costs. Common problems include coking, oxidation and discoloration during TIG welding process, titanium fabrication and welding of stainless steel pipes, tubes and tanks. | 10 ppm to 20.9% | N2, Ar |
