HALO H2O

HALO H2O

Trace Moisture Analyzer for Ultra-High-Purity Gases

The HALO trace gas analyzer provides users with the unmatched accuracy, reliability, speed of response and ease of operation that users of Tiger Optics analyzers have come to expect.

Features of the HALO include:
• Tiger Optics’ patented Cavity Ring-Down Spectroscopy-based trace gas sensor
• A very compact analyzer footprint
• Ability to measure moisture in most inert, corrosive and toxic gases with just one device
• Freedom from requirements such as periodic sensor maintenance, span calibrations, purifier replacement and pump rebuilds
