LaserTrace 2.5 H2O
High-performance ppt-level moisture detection
Delivering your best measurement
Detect gas quality upsets before they can damage your processes. Using Tiger Optics’ LaserTrace 2.5 H2O analyzer, you can verify moisture 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 2.5 H2O 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
