TDL600 NEC Opti PEAK TDL600 Moisture in Gas Analyzer NEC 05466

The next generation TDLAS Analyzer for automatic online measurement of moisture in variable compositions of natural gas and biomethane. The OptiPEAK TDL600 Tuneable Diode Laser Analyzer employs the latest techniques in laser absorption spectroscopy and signal processing power to offer a robust high performance analyzer, designed specifically for the measurement of moisture in natural gas. This non-contact technology requires minimal maintenance, even in demanding applications such as changing methane concentrations or sour gas. The analyzer is fully hazardous area certified and delivers class-leading measurement performance, stability and detection sensitivity.

• D-MET system: Factory-ready for varying gas compositions. For example, after stream blending or injection of shale gas or biomethane to a network.
• Operating range down to 1 ppmV
• Sour gas compatible
• Simple installation and setup
• Lowest maintenance
• IECEx, ATEX and cMETus certified for EExd flameproof
• Integrated sample handling
• Proven Michell Instruments quality: 40 years of expertize in moisture measurement built into the design
