Tracer 2™

Tracer 2™

The Tracer2™ addresses the need for accurate, reliable process controls, and moisture sampling at levels at or below single-digit parts-per-billion. It is ideally suited for ultra-high-purity moisture detection in semiconductor manufacturing processes, inert and specialty gases, component and system testing, and laboratory research applications.
Based on Faraday's Law of Electrolysis, the TRACER 2 sensor absorbs and electrolyzes moisture down to fractional ppb's. How? One hundred percent of the sample moisture is absorbed by aphosphorus pentoxide (P2O5) film that covers two spirally-wound electrodes embed in a hollow glass tube

Tracer 2™ Specifications:
