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.

Check out the findings from the GERG report on the use of a Raman Rxn4 analyzer and Raman Rxn-41 cryogenic probe for the reliable chemical composition measurement in LNG custody transfer applications.
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.
