This gas analyzer
has a two-laser platform
Two separate lasers are installed in the Model 5100HD gas analyzer (photo). They share a common optical path through the sample, allowing the instrument to measure two analytes simultaneously, which results in significant cost savings. The system is based on TDLAS (tunable diode-laser absorption spectroscopy) and can measure a combination of any two of the following: water vapor, CH4, H2S, CO and O2 in process or fluegas. The instrument is designed to handle sample gases with high dew points. The standard version has its sample cell heated to 100°C, and another version is available for 150°C. — Ametek Process Instrumentation, Pittsburgh, Pa.
