Description

The J22 gas analyzer uses patented tunable diode laser absorption spectroscopy (TDLAS) technology for accurate H2O measurement in gas applications. Featuring the reliable diagnostic capabilities of Heartbeat Technology, the J22 analyzer determines the concentration of a gas without coming into physical contact with streams. It allows pipeline operators and suppliers to meet quality specifications, prevent pipeline corrosion, and stop hydrate formation to ensure safety and asset integrity.

Field of application
  • Moisture measurement for natural gas production, storage, transport, and distribution
  • Applications including natural gas pipelines, processing, compression, gathering, and distribution
  • Real-time quality monitoring of biogas and biomethane
  • Reliable custody transfer measurements of gas quality
  • Controlling the efficiency of the gas dehydrator process
  • Fully compatible with hydrogen and CCUS processes
  • Measurable range options from 50 to 6000 ppm (2.4 to 284 lb/mmscf) H2O
Benefits
  • Ensures highest availability for production, transmission, storage and distribution of natural gas
  • User-friendly interface with intuitive menu and web server software
  • Integrated diagnostic and verification with Heartbeat Technology
  • Automatically-stored historical data and spectrum logging
  • NIST-traceable calibration providing superior accuracy and repeatability
  • Robust design for easy installation, commissioning, and repair
  • Field serviceable components and modules for minimal downtime
