Product Headline
An economical gas analyzer for moisture (H2O) in the natural gas industry. The sensor measures gas using tunable diode laser absorption spectroscopy (TDLAS) to determine the concentration of the gas without coming into physical contact with the stream. Option of simplified sample conditioning to reduce complexity of the analyzer system.

Field of application
Using patented tunable diode laser spectroscopy (TDLAS) technology, the SS500 analyzer is an economical choice for measuring H2O concentration in natural gas without coming into physical contact with the stream. The result is a sensor that does not suffer from contamination or drift due to vapor impurities such as glycol, methanol, or amines.
Natural gas quality measurements in production, storage, transportation, and distribution Monitoring for natural gas pipelines, processing plants, compressor stations, gathering sites, and distribution quality Suitable for use as a check-measurement deviceMeasurable ranges of up to 0-250 lb/mmscf (0-5275 ppm) H2O
Benefits
