LaserTrace 3 H2O
Ultimate performance for ppt-level moisture detection
Delivering your best measurement
Detect gas quality upsets before they can damage your processes. Using Tiger Optics’ LaserTrace 3 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 3 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
