HALO 3 CH₄

The HALO 3 CH₄ trace level methane 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 know and expect. Featuring Tiger Optics’ proven Cavity Ring-Down Spectroscopy-based trace gas sensor in a very compact and economic analyzer design, this versatile analyzer allows users to measure methane in most inert and passive 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 is ideally suited to many applications where trace gas measurement is extremely critical. These applications include silicon wafer manufacturing monitoring, fixed bulk gas continuous quality control, process tool monitoring, air separation, gas cylinder quality control and many other demanding applications.
