UHP GAS ANALYZER FOR PPT-LEVEL of H2O IN BULK AND SPECIALTY GASES
Looking for ultra-sensitive moisture detection in high-purity gas applications? The TIGER OPTICS™ HALO KA™ H₂O is the ultimate UHP gas analyzer, engineered to deliver parts-per-trillion (ppt) level detection of H₂O in bulk gases, specialty gases, and complex gas mixtures.
Unmatched Performance for Bulk & Specialty Gas Analysis
Designed for demanding environments like semiconductor manufacturing, the HALO KA H₂O uses proprietary Cavity Ring-Down Spectroscopy (CRDS) to detect trace moisture impurities as low as 100 ppt—even in challenging gas matrices like helium or germane (GeH₄) in hydrogen. Its fast response time, drift-free stability, and built-in zero verification make it a low-maintenance, high-performance solution for critical gas purity monitoring. Contact us for more information.
