TDLAS

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. Includes a heated enclosure for the sample conditioning system. Option of a simple sample conditioning system to reduce complexity of the analyzer.
