HALO KA H2O
Part-per-trillion detection limits for H2O
An analytical solution that’s right on time
The HALO KA 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 100 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 KA H2O specializes in trace-level moisture detection in bulk gases and specialty gases, as well as gas mixtures, including germane (GeH4) in hydrogen and other specialty mixtures used in semiconductor manufacturing. Pair the HALO KA H2O with the HALO OK for ppt level oxygen measurement to enjoy the benefits of laser-based technology for both of these critical contaminants.
Compact, affordable and powerful, the HALO KA H2O brings you:
- Parts per trillion (ppt) moisture detection capability in an array of gases
- Small footprint (two HALO KAs 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
