The HALO 3Q H2O packs a punch in one all-included compact and affordable package. Using Tiger Optics’ renowned time-based technology—Continuous Wave Cavity Ring-Down Spectroscopy—you can verify moisture impurity levels down to 120 ppt in helium, with drift-free stability and virtually instant response. You’ll find our system exceptionally fast to install, easy to use and effortless to maintain, with built-in zero verification. The HALO 3Q H2O specializes in trace-level moisture detection in bulk gases and specialty gases, as well as gas mixtures.
