Both MIG and TIG welders understand the importance of verifying that no oxygen during argon back purging or no argon CO2 blends are present.

At CO2Meter we provide a variety of industrial and welding gas sensing solutions that can be used to save time, money, product, and ensure confidence in the field.

CO2Meter provides a variety of sensing technologies that measure the presence of oxygen and carbon dioxide in welding and industrial environments.

  • TS-300 - Tecpen Weld Purge Monitor - provides accurate measurements down to 0% oxygen for back purging of argon during welding.
  • TS-302 - Tecpen Oxygen and CO2 Weld Purge Monitor - combines all the features of the TecPen Weld Purge Monitor with a CO2 sensor for MIG welding. This analyzer measures down to 0% O2 and up to 100% CO2.
  • COMING SOON! Stay up to date as more welding gas analyzers will be released in 2021!

"Easy to install, easy to set up, and easy calibration - just what I was looking for."
