Product Headline
Best-in-class gas analyzer for moisture (H2O) that is exceptionally reliable and tailored for the natural gas industry. The sensor measures gas using a tunable diode laser absorption spectroscopy (TDLAS) to determine the concentration of the gas without coming into physical contact with the stream. Heartbeat Technology ensures compliance and process safety at all times.

Field of application
The J22 gas analyzer uses patented tunable diode laser absorption spectroscopy (TDLAS) technology to provide accurate measurement of H2O in natural gas. 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.
For use in natural gas for quality measurements in production, storage, transportation, and distribution Monitoring and control in the natural gas pipeline, processing plant, compressor station, gathering site, and distributionIdeal for custody transfer measurements to ensure gas quality Measuring at the inlet and outlet of the dehydration process to ensure dry gas product quality in H2 production and CCUS applications Measurable ranges of up to 0-6000 ppm (0-284 lb/mmscf) H2O
