Delivering your best measurement

Detect gas quality upsets before they can damage your processes. Using Tiger Optics’ LaserTrace 3 O2 analyzer, you can verify oxygen impurity levels with part-per-trillion accuracy, drift-free stability, and virtually immediate response. You’ll find our system exceptionally easy and fast to install, and effortless to maintain, with built-in zero verification. It measures in bulk gases, specialty gases, and gas mixtures. And its robust design—free of moving parts—results in an analyzer that has a high Mean Time Between Failure (MTBF) rate and a very low Cost of Ownership (CoO).

Designed for trace level contamination analysis, the LaserTrace 3 O2 offers:

  • Industry-leading parts-per-trillion detection capability
  • Unprecedented speed of response
  • Widest available dynamic range
  • Absolute measurement (freedom from calibration gases)
  • Flexibility: up to four (4) measurement points per electronics module
  • Extremely low cost of ownership
  • Electronics module compatible with existing LaserTrace sensor modules


  • Gaseous CRMs & Calibration Gas Mixtures
  • High-Purity Gases & Systems
  • Research & Development
