HALO 3 H2O
Trace Moisture CRDS Analyzer for Ultra-High-Purity Gases
HALO 3 H2O CRDS Laser-Based Analyzer
The TIGER OPTICS™ HALO 3 H2O™ Trace Moisture CRDS Analyzer provides users with the unmatched accuracy, reliability, speed of response and ease of operation that users of our analyzers know and expect. Featuring our powerful Cavity Ring-Down Spectroscopy-based moisture sensor in a very compact and economic analyzer design, this versatile analyzer allows users to measure moisture in most inert, corrosive and toxic gases with just one device. Users also enjoy freedom from requirements such as periodic sensor maintenance, span calibrations, purifier replacement and pump rebuilds. As a result, the HALO 3 H2O analyzer is ideally suited to many applications where moisture measurement is extremely critical. These applications include fixed bulk gas continuous quality control, portable mobile analytical carts, process toolmonitoring, air separation, gas cylinder quality control and many other demanding applications.
