Mixing and analyzing: Thermco provides products for today’s processes


Thermco Instrument Corporation has been building its gas mixer and analyzer business through groundbreaking design and engineering for 66 years. Founder and gas analysis instrumentation pioneer Robert D. Richardson began the business in 1951 making specialty gas analyzers for the industrial gas industry.

When confronted with the challenge of finding a way to upgrade welds on US nuclear submarines in the 1960s, Thermco designed its first gas mixing system for welding shield gas that included a gas analyzer. Today the company continues to provide gas mixers and analyzers to meet the demands of new welding technology and applications, and markets its products globally, with partners in China, Indonesia, Japan, South Korea, Singapore, and Vietnam.
