Argon is a noble or inert gas with the symbol Ar and atomic number 18. It is odorless, colorless, monatomic, and unreactive toward other elements. It is the third-most abundant gas in Earth’s atmosphere, at 0.934%.

How can we help you?

Inerting and Steel Purification

Monitoring the argon (and nitrogen) flow rate for the bottom stirring of molten steel helps eliminate bubbles and other impurities. The proper mix of nitrogen and argon directly impacts the quality of the steel. Thermal mass flow meters with dual range calibration are a perfect solution for this steel or metal application.

Industrial Heat Treatment

Argon, helium, and hydrogen can be used in heat treating, where measurement will be required.

Thermal mass flow meters have a fast response and turndown to help control the proper mixture for heat treatment.

Leak Detection

Argon is used in leak detection where precision measurement or monitoring is essential, and thermal mass flow meters are ideal for this application.
