Moisture is one of the most critical contaminants in high-purity gas systems. Even trace amounts of water vapor can reduce product quality, damage sensitive equipment, poison catalysts, and negatively impact manufacturing yields.
Process Insights’ TIGER OPTICS™ Cavity Ring-Down Spectroscopy (CRDS) moisture analyzers deliver industry-leading sensitivity for continuous trace moisture measurement in bulk, specialty, inert, reactive, corrosive, and ultra-high-purity gases. Designed for demanding industrial and research environments, our analyzers provide real-time moisture monitoring with exceptional accuracy, fast response times, and virtually maintenance-free operation.
Whether you need parts-per-billion (ppb) or parts-per-trillion (ppt) moisture detection, TIGER OPTICS has a solution engineered for your application.
