O2 Monitoring

Oxygen (O2) is a colorless gas essential to life on Earth. It is also an important parameter to measure when attempting to improve combustion efficiencies in boilers and furnaces. In such processes, it is important to maintain consistent oxygen levels to avoid incomplete combustion and minimize CO emissions.


We offer TDLAS technology for O2 monitoring. Our instruments ensure accurate and rapid response to O2 levels in a variety of harsh environments. The Unisearch LasIR provides:

  • Reliable, accurate data
  • Rapid response – within seconds if desired
  • Multiple location monitoring for both fire detection and combustion optimization
  • Continuous emissions monitoring
  • Freedom from interferences from other gases which could result in erroneous data
  • Easy maintenance and improved process control
