An analytical solution that’s right on time
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.
Compact, affordable and powerful, the HALO 3Q H2O brings you:
- Sub-parts per billion (ppb) moisture detection capability in an array of gases
- Small footprint (two HALO 3Qs fit in a 19” rack)
- Absolute measurement (freedom from calibration)
- Low cost of ownership and great ease of use
- Wide dynamic range—over four orders of magnitude
- Clean technology
Applications
- Gas Quality Control
- Gaseous CRMs & Calibration Gas Mixtures
- High-Purity Gases & Systems
- Research & Development
