Endress+Hauser J22 TDLAS

Gas Analyzer

Proven technology for accurate and reliable measurement of H₂O in natural gas.

TDLAS

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 Laser Diode 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.
