The Model 331S measures H2S and/or Total Sulfur in natural gas, petrochemical streams, condensate, liquids, or LPG. Common applications include:
I.C.E. (Integrated Configuration Environment) is a Windows® based program that accompanies all 330S Analyzers for full configurability.

|SDS Dual Stream||The 331SDS Analyzer can measure two streams at the same time.|
|Total Sulfur||Total Sulfur furnace converts all sulfur compounds to H2S which allows the analyzer to measure Total Sulfur.|
|CO2||Dual-beam IR bench. CO2 concentration is displayed on the second line of display and can be configured as a 4-20 mA analog output. CO2 ranges from 0-20% to 0-100%|
|Stream Switching||Allows switching of four (4) input streams or from H2S to Total Sulfur measurement.|
|Dilution||Allows measurements up to 30% H2S using permeable membrane dilution.|
|Liquid Sampling||Liquid sample system to measure H2S in Hydrocarbon liquids or water.|
|Custom Systems||Envent can design custom integrated systems to meet your application requirements.|
