ReliablePrecise Rapid
2-Pack & 3-Pack H2S, H2O, CO2
Analyzer Systems Datasheet
For natural gas
Key Features
•One technology, one supplier
•Complete gas quality analyzer in
one small package
•Includes sample conditioning
and regulation
•No complex fiber or fiber optics
•Simple installation and
operation
The SpectraSensors H2S, H2O & CO2 2-Pack
and 3-Pack Gas Analyzer Systems retain the
analytical benefits and reliability known by
our existing customers. In addition, reduced
installation costs, support and complexity
are achieved via a single technology for gas
quality measurements.
Gas quality simplified The analyzer
system includes all required sample
conditioning and regulation. The sample
system is heated to keep all constituents in
vapor phase.
Training requirements are reduced and the
system enables fewer electrical runs, fewer
sample runs and less labor. Installation and
operational costs are dramatically reduced.
Sample probe options A variety of sample
probe products are available to compliment
the application. SpectraSensors offers
probes, probe regulators, and heated
regulators depending on the pressure in the
pipeline, the gas and ambient temperatures
and the hydrocarbon dew point.
•Fast and continuous
•Low maintenance, no light
source or probe replacements,
no tape and no carrier gas
•No field calibration
•Reliable in harsh environments
•CSA Class I, Div 2, FCC
Certifications
Applications
•Transportation Pipeline and
Sales Gas
•Raw Gas / Gathering
•Underground Storage
•Gas Processing, Dehydration and
Sweetening
