Tiger Optics describes the accompanying challenge of moisture detection.

Careful attention to detail paved the way to success for global gas provider Air Products and Chemicals, Inc., when it recently took the bold step of building the world’s first on-site, ultra-high-purity ammonia (NH3) facility, with a supply capacity of 2,000 metric tons per year.
