Field of application
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.
