Best-in-class Moisture Analyzer

SpectraSensors J22 TDLAS Gas Analyzer provides an exceptionally reliable measurement. It is tailored for natural gas pipeline operators and natural gas suppliers who want to meet gas quality specifications, prevent pipeline corrosion, stop hydrate formation, and minimize the risk of explosion to ensure human safety and asset integrity. TDLAS (tunable diode laser absorption spectroscopy) was introduced to the natural gas industry by SpectraSensors establishing the rugged nature of the laser-based analyzers. Our TDLAS analyzer technology has been used for decades in natural gas pipelines and requires very little maintenance. There are no interferences or detrimental effects from compressor oil, glycol, methanol, amine, H2S, or moisture slugs.


J22 Gas Analyzer



SpectraSensors J22 Gas Analyzer for H2O is extremely reliable and tailored for the needs of the natural gas industry. The sensor measures gas using a patented tunable diode laser absorption spectroscopy (TDLAS) to determine the concentration of the gas without coming into physical contact with the stream.

Rapid Response Time

The J22 analyzer takes four measurements per second with a laser and detector and immediately averages the results. Because there is no contact with the gas, real-time measurements are not hampered by wet-up or dry-down times as with surfaced-based sensors.


Trustworthy measurements are vital to a natural gas pipeline and processing companies. Uncertain measurements can be extremely costly. Additional processing of dehydration costs, upset conditions, shut-ins, and inconsistent process results may be caused by sensors that do not perform properly.

The highly developed algorithms of the TDLAS measurement plus the sophisticated diagnostics, monitoring, and verification concept of Endress+Hauser Heartbeat Technology offer a comprehensive process monitoring that cannot be found anywhere else.

Long Life

The TDLAS sensor does not come into contact with the sample gas stream. The result is a sensor that does not suffer from contamination or drift due to vapor impurities such as glycol, methanol, or amines.

Low Cost of Ownership

Operating costs are dramatically reduced by eliminating the cost of consumables, extra sensor heads, labor, and overhead associated with excessive maintenance.

The J22 dramatically reduces intangible but real costs associated with unreliable gas measurements. By eliminating added processing steps, detecting poor gas quality, and the possibility of costly damage to equipment that can result from sensors that produce incorrect data.
